Reading the review from DVDLaser.com, it seems the DVD will be missing:
-TV Special: Ford Star Revue in June 1951, is a 'making of' segment, hosted by James Melton, that shows the various steps in the development of Alice and includes preliminary animation and live action reference sequences. Here, even the clips from the completed cartoon are left in black-and-white.
-The CAV supplement opens with a brief history of Carroll's novel and a look at some of the book's original illustrations
-Following that is a fascinating collection of storyboards and a
script outline
-Live-action reference films
-The two CLV sides also contain about three and a half hours of audio material on the two analog audio tracks. One inclusion is an hour-long dramatization, broadcast on the BBC in 1951 with Beaumont and Disney. The format is fairly interesting, as it is 'Lewis Carroll' who not only narrates the story, but carries on a conversation with Disney about how much he admires the animated production. Also of interest--one of the performers blows a line in the middle of The Unbirthday Song and it takes a couple of seconds and another mistake or two before they get back on track. Another 1951 promotional show made for the BBC is also featured, which contains introductions to the songs but not the songs themselves. Songs from the film and songs that didn't make it into the film are also presented in extensive test recordings, many performed by the songwriters. Highlights include a musical number for The Lion and the Unicorn , the Mock Turtle soup lamentation (though it is not a lament the way they sing it), another version of the Mock Turtle's tale--somewhat more amusing--set to Blue Danube , a catchy rendition of the Lobster Quadrille entitled Will You Join the Dance , and Speak Roughly to Your Little Boy . What much of this shows is the searching through of both Alice in Wonderland and Through the Looking Glass that Disney's team did to find the most potent passages and best mix for translation to film. The listener can judge whether or not they succeeded or if, indeed, they ever came close. The film is charming and the disc is terrific, but it is clear from the materials presented that a lot of compromising went on to make Disney's dream a reality.
Why, Disney, why?!!!!
Keep in mind, however, that this would be the only case for a Disney movie (unless "Alice" proves otherwise) of a song that was written, recorded and partially animated for the original release, but abandoned because of (I'm sorry) impatient, short-sighted test audience members that caused the song to be abandoned half-way through only to be edited back INTO the film for its special edition. If any of you have seen the animation of the sequence, it's beautiful. John Pomeroy and Glen Keane really shone through (as the animators of John Smith and Pocahontas respectively), and I say again I would be THRILLED to have it put back into the film. I'll buy Alice with a new song if it helps this happen.
Why didn't Finding Nemo open like a book 
Thats really neat when they do that 
Just like 
mouse's Birthday
