But all you George Lucas haters out there: would you change your mind if Revenge of the Sith turns out to be a masterpiece, he releases the OT on DVD, and then he makes SE's of the prequels, fixing all the stupid plot points, and denies that the original prequels ever existed?

I think that when he gets some time to really think about things, he'll release the OT on DVD. If there's one thing he is, he's very clever at marketing. I think he's just waiting and waiting for demand to build up, and he has no need to release it now, with his prequels. He needs a way to make money later on (despite the millions he has already).
