Richard Marquand being dead didn't stop George from messing around with RotJ.
But honestly, I wouldn't be surprised if Disney puts out a blu-ray set that's just a restoration of the unaltered OOT. I can't see anyone complaining about it except for those anxiously awaiting yet another revision, and they'll probably end up buying it anyway. Yes, Disney would probably jack up the price, but at least they wouldn't be forcing the OOT fans to pay for something they don't want.
Ideally, each individual movie would get its own multi-disc set and be an archive of all the theatrically released versions. And yes, I do think this 4K scan will be used to make George's final version of the I-VI saga for a 3D theatrical re-release (TPM's already been "finalized").
When we remember that the movies still don't have individual blu-ray releases (just the two trilogy sets), this starts to seem like more of a possibility. I think they know how strong the SE backlash is, though. That's why I doubt they'd bother including anything other than the "most recent" version (from this new 4k scan) because they know what people really want is the restored OOT.
