I can confirm that they do indeed have two ESB faded 35mm prints, so this is not the hoax you are looking for. Move along, move along...
I can also guarantee that there is a 4K scan of an ANH print coming one way or the other, there is an Australian print around, so no need to stress.
I am not part of the team, but I can verify that the ESB stuff they are showing is for real and not some faked stuff. How far along they are with ESB I have no idea.
