I think putting SW out on a two-disc set is the way to go, considering Lucas' relative intractability concerning the old version; it's somewhat amazing he's even doing it at all, really. But I really hope it will not be subjugated with a "disc 2" label on the disc itself, or worse yet "bonus material", because that is disrespectful. The tone of the press release seems to indicate that would be the case, unfortunately. Oh well.
I'm sure various 'ultimate versions' could be made offering choices of audio and fixing what screwups they might make, if any. For my part I'd like the '85 stereo mix primarily, because that's what I grew up with on VHS (and is why I got the Editdroid), but having the mono would be interesting for the sake of comparison. I've heard only small bits of it via the classic edition. Having all the sound mixes plus music-only would be excellent. There will yet be many possibilities for editors come this fall, methinks . . .
