I was just about to say that. They're milking as much as they can out of Star Wars fans with the current DVD format, and probably could rerelease some of these versions barely changed on either Blu-Ray or HD-DVD (only now maybe on fewer discs or better quality).
It'd be nice if we could get a format that would be large enough to hold everything on ONE DISC. ALL the Star Wars movies, all versions of them, all other related Star Wars material like Clone Wars, the entire series of the upcoming Star Wars TV shows, every DVD extra ever made, all in the highest possible better-than-actual-film resolution, THX uberrerereremastered, and all the PC games on it... There couldn't possibly be a better version, until Lucas (or most likely someone else by this time) makes something else that has to do with Star Wars. >_<
