The Last Jedi and Solo are already available on UHD. I see the previous Marvel movies are being released on UHD. The Force Awakens and Rogue One can’t be far behind. I’d expect the Original Trilogy special editions to arrive on UHD eventually. I see nothing to cause expectations for the unaltered versions.
I’m fine with the versions of Rogue One and Solo we have. No need to muddy the waters with special editions of those movies as well.
I’d love to get The Force Awakens and Rogue One on UHD, but I will not by the special editions of The Original Trilogy again, ever. I think the prequels (AotC and RotS) would have to be upscaled from 1080p for release on UHD so also not interested.
The only reason I’d sit through the special editions again would be if they released them in 3D theatrically. I’d watch them just to see the trench run, walkers on Hoth, and speeder bikes all in 3D.
You don’t want to see any of the alternate footage shot that was scrapped? There’s practically two alternrate versions of these films.
With five versions of Blade Runner in existence I don’t see how alternate cuts of R1 and Solo is going to muddy anything.
