Disney is not legally obliged to give a shit about Lucas’s wishes–he gave that up when he sold everything for billions of dollars–and it certainly isn’t doing it to spare his feelings. That’s absurd. It also ignores the fact that Disney threw out all of Lucas’s ideas for the sequel trilogy without a care and he was so unhappy with the results that he whined about selling Star Wars to “white slavers.” He has no power anymore or even the slightest influence. So no, I can assure you that is most definitely not the reason we haven’t seen the OOT yet. They’re either working on it until they can get a perfect restoration to satisfy everyone or they’re sitting on it until the 40th anniversary or some other ideal time to milk it. If they aren’t doing it at all, it’s for legal reasons. And they’re likely attempting to sort those out if so. The only other explanation would be outright incompetence and failure to see the massive market and cash potential for them. Which I sincerely doubt considering even the projects of this site have made major news. They also prove that, clearly, technical difficulties aren’t holding the project back, or at least they are not a valid excuse. If even fans can undo the changes with highly limited resources, Disney certainly can. It wouldn’t even matter if Lucas destroyed all the original negatives. They could just cobble together the best sources possible for everything missing and “despecialize” the 97 print themselves. It wouldn’t be ideal, but it would still beat Harmy and crazier things have been done in restoring old movies.
