Like I said before, I could totally see them putting out a regular 1080p blu-ray of the OOT this year because of the guaranteed dollars it would bring in, even if they have to share some of it with Fox. They would still have a UHD in their back pocket waiting to be released after May of 2020.
This possible scenario makes the most sense to me.
Apparently none of this has anything to do with sense, though.
