The April 6, 2010 Blu-ray release will contain only the theatrical editions of the films, NOT THE EXTENDED EDITIONS . According to Wikipedia* :
On April 16, 2009, Warner Bros. announced that it would be releasing the theatrical versions of the trilogy on Blu-ray in a boxed set later in 2009. Jackson also said that the Extended Editions were in development for Blu-ray and would be released in conjunction with the theatrical release of The Hobbit in 2011.
In July 2009, Jackson announced in an interview that the Extended Editions will be released sometime in 2010 on Blu-ray with possibly new special features to be made.
On December 14, 2009, it was announced that the three films will be released on Blu-Ray on April 6, 2010. The press release stated that the extended editions will be released "at a later date". Alongside the Blu-Ray announcement, it was announced that the three films would become available for digital purchase for the first time on all major digital service providers.
* Many filmed scenes remain unused, even in the Extended Editions. Deletions include:
The Fellowship of the Ring
Additional footage from the Battle of the Last Alliance during the prologue.
An obscure shot from the trailers of two Elven girls playing about in Rivendell.
Scene mentioned in the commentary, about an animal disrupting Frodo and Sam while they sleep, after seeing the Wood Elves. Many animals were used, including rabbits and deer.
Dialogue from the Council of Elrond, such as Gandalf explaining how Sauron forged the One Ring.
An attack by Orcs from Moria on Lothlórien after the Fellowship leaves Moria. Jackson replaced this with a more suspenseful entrance for the Fellowship. Much of the lost footage can be seen as promotional material on The Fellowship of the Ring theatrical DVD and tie-in books, documentary footage on the Extended Editions, and Trading Cards.
Longer scene of Boromir trying to take the Ring.
Frodo seeing more parts of Middle Earth when he put the Ring on.
More battle footage from Parth Galen.
An attack on Frodo and Sam at the river Anduin by an Uruk-hai.
The Two Towers
More Arwen footage, including a flashback scene of her first meeting with a beardless Aragorn (seen in The Two Towers trailer).
Faramir having a vision of Frodo becoming like Gollum.
Footage of Arwen at Helm's Deep, cut by Jackson during a revision to the film's plot. Foreshadowing this sequence were scenes where Arwen and Elrond visit Galadriel at Lothlórien (seen in The Two Towers trailer). The scene was edited down to a telepathic communication between Elrond and Galadriel.
Théoden speaking to the troops in the armoury, prior to the Battle of Helm's Deep.
Éowyn defending the refugees in the Glittering Caves from Uruk-hai intruders.
An unknown scene displayed in The Two Towers trailer of Éomer lowering a spear while riding his horse in a forest.
Frodo and Sam fighting on the ground in Osgiliath (after Sam tackles Frodo away from the Ringwraith). The scene's fighting was deleted, but Frodo drawing Sting and pointing it at Sam after he is tackled was left in.
The Return of the King
A line of dialogue during the death of Saruman, in which he reveals that Wormtongue poisoned Théodred, giving further context as to why Wormtongue kills Saruman and Legolas, in turn, kills Wormtongue.
A conversation between Elrond and Arwen in a library in Rivendell, after Arwen decides to wait for Aragorn. Elrond leaves, saying, "You gave away your life's grace. I cannot protect you anymore."
Sam using the Light of Eärendil to pass the Watchers at Cirith Ungol.
Aragorn having his armour fitted during the preparations for the Battle of the Black Gate. This was the final scene filmed during principal photography.
Sauron fighting Aragorn at the Black Gate. A computer-generated Troll was placed over Sauron due to Jackson feeling the scene was inappropriate. Sauron is also seen in a beautiful form as Annatar, Giver of Gifts.
Also at the Black Gate sequence, Pippin was seen in the trailer holding a wounded Merry.
Further epilogue footage, including that of Legolas and Gimli, as well as Éowyn and Faramir's wedding and Aragorn's death and funeral.
Peter Jackson has stated that he would like to include some of these unused scenes in a future "Ultimate Edition" home video release (probably high-definition) of the film trilogy. They will not be re-inserted into the movies but available for viewing separately. This edition will also include outtakes .
I know how some people are and the idea of veiwing separately may not be a good idea . There will be those who will do DVD editing to make a complete DVD and they will try to sell it . The best laid plans of mice and men soon go awry . So what is the plan now ?... * from LOTR trilogy info of Wikipedia

If you go onto the official site, then press the link at the bottom for Return Of The King on DVD, a Warner Bros online shop page opens up, and on that is a picture of a Lord Of The Rings blu ray box set, for sale on pre-order with the date 11/3/09, but i have searched HMV, Amazon and a couple of others and they have nothing at all apart from the DVD's. Must be a mistake, also it looked like just the theatrical versions, for me, the extended editions are the proper versions now.

I have just bought the Samsung 7.1 blu ray home theater system, and though i own some good films on blu ray, and they look good and everything else, the ones i'm really waiting for are the Lord Of The Rings trilogy.
I would like to see a box set of the extended editions with the existing special features, plus some new ones, maybe a look back at the legacy of the trilogy documentary with the actors and key personel behind the camera.
For the films themselves, obviously they won't be split into two no more and the whole film will be on one disc, maybe making room for the theatrical releases to be included, bit like they did before with the special editions, but for me personnally, i'm not fussed about the theatrical versions, as i would always only watch the extended versions.
On the technical side of things, the picture should be the best they possibly can transfer it, and the sound should be a choice from 2.0 through to 7.1 TrueHD. Prince Caspian, though not a great film is in 7.1 on blu ray and its the best i have ever heard a film, including at the cinema.
Though it's taking it's time to come to blu ray, i think its because its being done properly, which i don't mind waiting for.
I'm purposely not watching my Lord Of The Rings DVD's, and it's been a year now since i last watched them, the longest i've gone without, because i want it to be special again when they're finally released on blu ray, and i have my perfect Lord Of The Rings night in.

*Lúthien is jealous* lmao

Willdoo

Have fun with your Blu-ray! We don't have a thingy to play Blu-rays on yet. Damn.

I'll also be waiting for the extended discs on blu-ray... upscaling works well on the DVD's in a PS3 anyway.

Yes, we fans (or nerds) deserve it!

Theatrical release only, though. Personally, I will wait for the extended version or a combination package. My understanding of the tech. is limited, but most feel (and I agree) that both versions can be put on 1 dics with room to spare and that this is simply a way to double dip when the extended version gets released at a later date (sound familiar?). I can wait them out! The tech. doesn't justify the costs: $70+ ($140+ for both) purchase of a movie i've seen 100 times over regardless of how much i love them. Newline is a greedy scammer...just release the both together, we fans deserve it!

"Check it out:

The Digital Bits.

Here's some news that's going to thrill a whole bunch of you Blu-bies. Warner has revealed, in a promotional insert packed with the new Poltergeist Blu-ray Disc, that it's currently working on a Blu-ray version of The Lord of the Rings: The Fellowship of the Ring! No s--t! Not ONLY that, but the same insert lists The Wizard of Oz, Being There, Gone with the Wind, King Kong, Woodstock, Rush Hour, The Notebook and Amadeus all as coming soon to Blu-ray! How do you like THEM apples? What's more, our industry sources tell us that ALL THREE Lord of the Rings films are planned for release in Blu in 2009, though we're not yet certain if the discs will be the theatrical editions, the extended editions or both. Still, if that isn't enough reason for some of you holdouts to run out and pick up a player this holiday season, I don't know what is. Here's a look at the actual insert (not that the image links to the official Warner Blu-ray website)..."

I'd be happy if they do!

Hmmmm... to be followed-up I guess...

I read somewhere that maybe late 2009, fellowship will be released on blu-ray, don't know whether its the theatrical or the extended one, i hope the extended one.
By what i read, it seemed as though they wanted to release, one a year, a bit like when the originally released them at the cinema, and i suppose once they've done that, we'll get a new box set released the year after that. So there's a bit a life in the old trilogy yet.
All i done was type in Lord Of The Rings on blu-ray, on google, i didn't even www dot it or anything and out of the list of sites it gave me, i can't remember what one it was, but i read on one of them.

Check torn,i cant cuz they 'kindly' banished me.

Check torn,i cant cuz they 'kindly' banished me.

I have had no idea, other than rumors that they may do something like that after they release the hobbit

No, but that would rock! I could get it extended!!!!!!!!!!!!!!!!!!!
