It will sadly / probably never happen . . period. . .which is why we should all take it upon ourselves to re-create the trilogy on our own using the preexisting physical media, similar to what Harmy did at the very least. You’d be amazed how through cut / paste methods of the many different available sources, you could re-create shot for shot. . .these original 3 movies. . .and make them look exactly how you want them to be.
All you need is little ambition and creative “know how” 😉
