It’s fantastic news, and the restoration looks like the best and most detailed picture quality yet seen. I’ll be there opening night, and buying the 4K.
Like Omne above, I’d also like the restoration to be applied to some sort of definitive edition because there are many small elements within the Special Editions that I would miss (the scene with Biggs and Red Leader, the rebel fighters approaching the Death Star, the open vistas of Cloud City, the Bantha herd before the sail barge). But there’ll never be an official new cut that keeps the good bits and jettisons the bad bits (or even unilateral agreement on which SE bits are good or bad). I guess that’s what fan edits are for…
