I'm a newbie here so I could be wrong, but surely it couldn't be 4k? Or if it is 4k it would be a big deal for the original trilogy?
My understanding is that the scans of the original trilogy, were all done at 1080p, just under 2k. So if Disney have a 4k screening, they would have had to rescan the negative?
Also, werent the last two prequels shot at 2k or under, so they would be impossible.
