Just a thought here, but like if a 4K Blu-ray release does really come out, isn’t it going to be impossible to use it as a basis for any further fanedits or preservations?
Best of my knowledge, there’s no way to RIP a 4K disc yet, or at least ripping an exact copy of it.
Nope, rips of UHD discs already exist. I have no idea what the method is though.
