SW: Do you think we’ll ever get the original trilogy and the prequels without any changes on Blu-ray, or is it never gonna happen?

McCallum: I would have to answer that officially it’s never gonna happen, but you never know with George. It’s one of the constant things that—let’s put it this way, it changes always. You never know.

SW: Yeah I mean personally, as I’ve said many times on the site I have no problems with George changing the films, I just think it would be great if he would release the originals and that way everyone could have it, but that’s just me.

McCallum: I know, but I understand that completely. It’s just a question I can’t answer. Obviously I have my own personal feelings, I hope that he does it, but I don’t have major arguments with him about it. I think that’s a decision he has to come to on his own as time comes by.

"If he released them, that way everyone could have it." Never thought about it like that before... that's brilliant. ;) Seriously though, it doesn't get more clear than this, McCallum says exactly how it is compared to the excuses we hear from Lucas from time to time. He says that officially it's never going to happen, if only Lucas could be as sincere.
