If Lucas never releases them ever again, then they will become a collectors item, but not in a monetary sense. 10 years from now after the 2007 SE with more changes, and in say 2011 BlueRay HD-DVD with even more changes, alot of new fans may be curious as to what the original version, now 5 versions ago looked like, so for curiosities sake, they may buy them on ebay just to have them as a completist SW fan would want.

I still think they will be released fully remastered, cause the Superman II: Donnor cut is coming out next week, and that took 25 years for fans of this supposed edit to see the light.

Just remember guys, it aint about vision, it is about money, whether it be the release last September, or the Donnor Cut, these movies are released for one reason only: $$$$$$$$$$$$$$$$$$.
