At the end of his presentation, George Lucas took part in a media Q&A backstage. Miguel sends in the highlights:
The all digital version is longer, I believed he metioned a dagobah scene in that version but not in the regular theatrical version.
He confirmed 2 TV projects: One is continuing with the Clone Wars cartoons and the other is the live action series.
Another box set is in the works: Looks like a 6 disc box set with all episodes 1-6. Possibly a 7th disc, maybe with deleted scenes from the original trilogy. He was asked if he would be changing things again in the movies, prequels or original. He replied that everything is the way he wants them now. As far as the rumored super archival edition due out in 2007 on super hi-def dvd, there is no truth to that.
He really wants to rerelease the OT back in to theatres via the new 3-D technology.
