he cleaned up film version was so sparkly that we were blinded by the fact that Lucas altered EVEN MORE to the original trilogy
Naaah, the fact extra stuff was added was touted in almost all those magazine interviews. It was typically the lead-in to the poll you cited. "Lucas again has tinkered--which is interesting since according to this poll, 60 percent of people would like the originals on here as well" But it wasn't hidden, certainly not by the reviewers and writers, even the TV critics and such.
I wouldn't call "Robot Chicken" and a 2 year old South Park episode "hype" either. but people ARE aware. And LFL Marketing DOES want the originals out there. They've been fighting for it for a good 4 or 5 years, I know that. They just can't get it done. Whatever this "Archival Edition" that (supposedly) closes the book FINALLY on the Star Wars movies is their best chance to make money on those old versions, which is what they want to do. They'd LOVE to be able to sell you another version of Star Wars.
