The point is that doing a straight digital restoration and claiming that the 1997 SEs are the same thing as a digital restoration is just plain false.
You're right about one thing though. GL should release the 1997 SE for the people that want that version. Maybe one day we'll get a giant box set that'll include every version of Star Wars ever released. Of course, Lucas will have to rerelease it every year as he makes more and more changes.
