regarding the ultimate editions. I have it from several sources whom I trust that they are in the works. Of course nothing is certain, after all LFL annouced a raiders of the lost ark special edition (yep just like the SW trilogy) for last year that was suppose to go to theatres. It never happened. ANd that was offically announced.
I would stake my rep that there will be a 2007 SE for the OT including new changes such as inserting Bail into ANH, replacing the ESB emp with Ian McDiarmid and putting the imperial march into ANH.
