Since Disney owns SW now and George is letting go, I think we’re in a better place than ever to hope for this. I do think we’ll see the original trilogy restored and released on blu-ray and internet digital release someday.
JJ Abrams recently has been restoring the 70s horror movie Phantasm, just because he’s a big fan of it. With somebody like him around, I would not be surprised if somebody like him cares enough to lobby for getting the original trilogy restored and released.
