I still think that if Disney does release a proper restoration of the OOT, it'll be before Episode VII, or at least before we get too far into the ST. If they wait too long then OT fans will really hate them just like Lucas, and I think they want to try and win over every Star Wars demographic before these new movies, then again I could be wrong because 'decanonizing' the EU was pretty bold, but I'm sure anyone interested in the EU will still go to Episode VII anyway. I still really doubt that they will consult Lucas about the OOT or anything related to the previous movies; Disney won't pay someone 4 billion dollars just to be held back by some confusing nondescript "vision" that's always changing. Basically what I think is that if Disney wants to release the OOT, they will, and if they don't want to, then they won't (although I can't imagine why they wouldn't want to).
