If Disney releases all three original films unedited from their original theatrical versions in a simple, 3 disk blu-ray box set in the highest quality possible... that's the only thing good that could happen.
If they finally do the originals justice, then it's worth it as far as I'm concerned. Even if the sequel trilogy is complete garbage (i.e., almost as bad as the prequels EDIT: the English language lacks the words needed to describe how terrible they were), at least the originals will be there. Who knows? Maybe 7, 8, and 9 will be decent movies, but it won't be the same (and we all know it).
What I really don't get is this: From a business perspective, it's a really good idea- I guarantee it will become sold out before you can blink. Maybe asking/petitioning Disney will work. They own Lucasfilm now, right? Does Lucas still own the original films?????????
