The way I see it, there are two versions of Star Wars worth preserving for history’s sake: the '77/'80/'83 and the '97 editions, the only two that saw their premiers on the big screen. As far as I am concerned, the '04 DVD and '11 Blu-Ray cuts are insignificant from a preservation point of view.

If new Lucasfilm lead by Disney wanted to put out their own edition based on the '04/'11 as some kind of “Definitive Edition,” like the Bladerunner “Final Cut,” why not? It would be better than anything we’ve had since the original releases (they would be bone-headed, for instance, to keep Greedo shooting or Vader’s Noooooo!). If they’re doing a new 4k transfer for such purposes, however, there is no excuse not to release the theatrical version alongside, and from a business perspective, it would be quite stupid to pass up the opportunity for an expensive boxset that would fly off the shelves.
