What John Landis’ story says to me is that George doesn’t mind the idea of the original versions being out there.

It’s not his money being spent anymore and that was pretty much the only reason we got the GOUT instead of an hd remaster like they did for the '04 set.

Now he has no reason to care.

As for the 2020 thing, well, it’s not like they’re going to stop re-releasing these movies on home media. They eventually got around to the digital platforms in 2015, throwing in some exclusive bonus features as an incentive.

I honestly don’t see them releasing these movies at all on 4k UHD until enough people have adopted the tech. It’s what they did for dvd and bd and digital. Although one unknown factor in all of this is whether or not Disney wants TFA and RO on UHD without the fans who’ve upgraded being able to experience I-VI that way as well. I’m reminded of how fans were stuck watching the OT on vhs as TPM and then AotC were released on dvd, and then still for a couple years after until 2004 less than a year before RotS came out.

Maybe they’ll pull something similar and wait until 2018 or early 2019 to release the OT on UHD as part of the marketing push for Episode IX, although I suspect Fox wouldn’t want any featurettes referencing the Disney movies.

So who knows when it comes to the OT on 4k.

The OOT on blu-ray is a different story, though. I could see them releasing that in the meantime.
