The only potential problem (from Fox and Disney’s end of things) with waiting until 2020 is not being able to sell us anything new in the meantime. Disney is conveniently side-stepping this problem with the digital release and the tnt deal, but that only covers non-physical (and non-theatrical) media.

I don’t see Disney waiting too much longer to put out their own movies (TFA, RO) on 4k Ultra HD. Once that happens, the fans are going to wonder what’s going on with the OT. It will be like what happened with the saga’s release on dvd where GL wanted to wait until RotS was also hitting the format, except this time it may actually happen with Episode IX and for entirely different reasons. It’s going to piss off some of the fans who want to enjoy I-VI in the highest quality possible as they wait for Episode IX, which is why I could see Disney authorizing a UHD release within the next couple years and simply letting Fox take their cut.

But now we’re back to the whole problem of people not really giving a shit unless the OOT is restored as well.

Which presents yet another dilemma for Disney. If they do acquiesce and release the OOT in the next year or so, even if it’s just on regular blu it leaves them with one less thing to sell people for the first time post-2020. Not as many people are going to want to rebuy it on UHD.
