While I won't be able to contribute directly to any talk of the new Star Wars (I'm not seeing it until at least DVD--sorry Lucas, you screwed up with that last one), I saw this link today. The guy makes a really interesting argument that Vader and the Empire were the good guys, while the Rebels were the bad guys.
Then there's always this fun article from a few years ago about the Luke Side of the Force. Makes sense to me, but then I'm not sure how it fits in with the prequels.
