I don't feel like anything has changed. An entire popular media format was born and died without the originals ever getting a proper release. There is nothing new here.

My best childhood friend's younger siblings haven't even seen the originals (I just realized this depressing fact a year ago when I went to visit his family). He and I had always been huge Star Wars fans, when he moved out of the house taking his old VHS set with him his family replaced them with a 1997 SE VHS set because that was what was available. These kids are in college themselves now, and have never known anything but the '97 SE. The originals have already been suppressed to an entire generation.

The 2004 set came out seven years ago, that is the only Star Wars children of the DVD generation have known; unless they happen to have accidentally popped in the bonus DVD from an '06 set or have parents who know the difference between the versions and care.

Unless they have parents who are big enough fans to care about the difference between SE and OOT, the vast majority of kids aren't going to be exposed to the unaltered films. It is that way now, and it will be that way on Blu-ray. Even if the OOT is released on BD someday, that still isn't going to change.
