I'm happy about the O-OT coming out on DVD, but from the sounds of it, Lucas is doing his own transfer from Laserdiscs, even if it is the masters. After seeing how things went for the '04 DVDs, Lucasfilm is good at messing things up, such as-will Luke's lightsaber be the right color on the falcon, etc. Also, will they do anything for it as far as cleaning it up, or will it just be a straight transfer from LD, which, as others have said, usually doesn't produce great results, especially if this is just some slopply-done rush job to have yet another release. This may be the best thing we've seen, or it could be something that isn't even as good as some of the fan preservations.
Also, I would love to see a release with some of the different sound mixes on it, such as:
Star Wars:
Dolby Surround
Mono Mix
ESB:
35mm
70mm
I don't remember off the top of my head if ROTJ had any differences in the various sound mixes.
