It’s got to be the Maclunkey version, especially after that Kathleen Kennedy speech about the BFI print being super rare and whatever. Even the name has been revised again! The sequel trilogy era convention of losing the numbered episode is still in effect.
Edit: the online press thing claiming this is a “once in a generation event” is weird too. Like, is it the 1977 version? If it’s not why is this such a special event? If it is are they going to put it into a vault for a few decades and not stream it until a new generation grows up? What are they talking about?
