Maybe I’m missing something but the use of “original” seems a bit misleading.
I’ve read all the linked articles including Edward’s interview, and nowhere does it specifically state it’s the OOT version of the film, just a lot of speculation and guesswork. The articles jump between referring to the film as “the original Star Wars” and “A New Hope,” so I don’t think they’re alluding to an OOT version as much as they are specifying which film it is.
Unless I’ve overlooked something I’m willing to bet it’s the 2011 version remastered in 4K.
Either way we’re not going to know anything until we receive official word.
