There’s no way they would remove the logo and fanfare from an OUT release. They would present the movie as close as possible to how it was (at least to the layman if not nitpickers like us), and the iconic fanfare’s absence would be quite a glaring omission.
It’s the SE I was referring to in my post.
I don’t think the 2020 thing makes a difference in terms of the Fox logo showing up on the original versions of Empire, Jedi and the prequels. Disney will own those movies outright after 2020, yes, but I don’t think that legally prevents them from the fox logo showing up in a restored OOT. Think of all the catalog titles now owned by different studios than the ones who originally produced/released them. I’m thinking of all the MGM movies now owned by Warner Bros because of Ted Turner, the Hitchcock titles originally produced by Paramount but now distributed by Universal, or the DreamWorks movies now owned by Viacom because of the folding that happened roughly a decade ago.
The rights issue with Star Wars is a two-way street anyway as we’ve discussed, since Fox owns all versions of the '77 film in perpetuity.
