Going with the logic that CE3K successfully pulls off the 3 full movies on one disc, let's speculate on how 100gb would be divided up for Star Wars (ANH)

(Video-75gb : Audio-14gb : unclaimed-10gb)

Video A : 25gb : George's Current Version

Video B : 25gb : Theatrical

Video C : 25gb : Special Edition

Audio A : 2gb : George's Current Version

Audio A1 : 1gb : New Commentary

Audio B1 : 2gb : Theatrical 70mm

Audio B2 : 2gb : Theatrical 35mm

Audio C : 2gb : Special Edition

Audio C1 : 1gb : 2004 Commentary

Audio A1,B1,B2,C1 : 4gb : Isolated Music Scores

Additional Options : 5gb : ____________

(internal necessary bluray format files) : 5gb

If anyone's worked with the format, play with the numbers. Otherwise, that's not much space left over to do much. Could get a low quality doc. in that space. Now in the minds of Lucasfilm, do you think they feel it's advantageous to go with 12 discs over 6, so that Documentaries can be added, as past DVDs have done, or would they eliminate the theatrical versions to have the set be 6 discs. How do we show that the buying public is interested in have a complete all versions of the film + Bonus stuff. The CE3K Sluggo mentioned is a two disc set and it's going for $20, that would make this SW set over $100-$120. Although the Blade Runner (5 disc set) was originally $40.
