Well as I understand it, there are a lot of complications regarding Fox's distribution rights to Star Wars, plus there just isn't a broad-base consumer delivery option for 4K... plus, I mean... we don't KNOW that there's any change-of-heart regarding allowing the OT to return, we just all hope that greed/profit/nostalgia/whatever has a chance, now that George isn't in sole control of the property.
But also, as I've said many times, knowing what I have to do to get these kind images out of great prints and wonderful scans, then even with original elements it would require a restoration unlike any other. It would take more time, more people, more money than I've ever heard done to a commercial release... I mean, there's no way around it. Even with original elements, the hardest shots are shit-tons of work. I dunno... we have no reason not to stay hopeful and positive, but also no reason not to hedge our bets.
