…Lucas has literally no say at all, let alone being the only one who can decide. Not sure how many times it has to be said: Lucas is gone. He’s out. He has nothing to do with Star Wars any more in any capacity whatsoever. For all intents and purposes, he might as well be dead already. He has no decision-making power of any kind over the franchise. If anybody is holding an OUT release back, it is likely Fox.
Besides, Lucas released the OUT. He gave in. It was crappy, yes, but it proved that what was holding him back was likely not some kind of “artistic” principle that the SEs remain the only available version, but rather that he was too lazy and cheap to restore the OT. Now he no longer has any reason to care. He won’t be doing the work or footing the bill. He got 4 BILLION dollars to get out of the way. There are no stipulations with that kind of money. Lucas is out, and I think he’s relieved to be out too.
And again, doesn’t make sense that they would include the SEs that reference the prequels if they aren’t including the prequels. And it IS relevant that JJ prefers the OUT, and Disney themselves have clearly emphasized the OT era. They are the ones who created TFA, which was clearly designed to emulate the spirit of the OUT. So yes, it does make some sense that it would be paired with them if Disney are the ones making the release.
