I don't think he will, because I think the color changes were deliberate and even if they were a mistake, George Lucas has too big of an ego to admit he made mistakes and own up to them. I know the '04 DVD was a rushed release, but come on, how shitty can you get? It's obvious at the last minuet, GL decided to have the set come out in '04 instead of '05. It made a lot of sense to have them come out in '04 instead of '05. That meant more ticket sales for ROTS. He compromised quality for $ and for the greatest movies ever made that is unacceptable. I doubt he'll even bother correcting any of the continuity errors for the blu-ray release.
I love everybody. Lets all smoke some reefer and chill. Hug and kisses for everybody.
