Wow, way to drag up a 3-and-a-half year post! I'd forgotten I've been here for that long ...
My points still stand, though. Now I'd probably change it - for practical purposes - to be disc 1 super ultra final cut, disc 2 1997/color-and-audio-fixed 2004 cut, disc 3 original 1977/1980/1983 theatrical cut with selectable crawl for SW and 70mm seamless branching for ESB (I'm fairly certain now that there never were any 70mm differences for Jedi). Then disc 4 is all trailers, deleted scenes, etc.
Granted, I'd never put in discs 1 or 2, but it'd be nice to get the Blade Runner/CE3K treatment for each film, no?
To go even further than an OOT set, I give you the complementary PT set:
TPM
Disc 1
- Super Ultimate CG-Yoda Cut
- New Surround Mix
Disc 2
- Seamless-Branching 1999 Theatrical/2001(?) DVD cut
- Original 1999 5.1 for theatrical cut
- DVD 5.1 for DVD Cut
Disc 3
- All 2001(?) DVD features, plus new ones
AOTC
Disc 1
- Super Ultimate Cut
- New Surround Mix
Disc 2
- Seamless-Branching 2002 35mm/2002 DLP/DVD/IMAX Cuts
Disc 3
- All DVD features, plus new ones
ROTS
Disc 1
- Super Ultimate Cut
- New Surround Mix
Disc 2
- 2005 Theatrical Cut (only difference between theatrical and DVD is one cut vs. wipe transition)
Disc 3
- All DVD features, plus new ones
Not that I'd buy any of those 3, but there you have it. I'd also like to add that I'd never buy a 6-film set - they should keep it as two separate 3-film sets, PT and OT.
