Just a note about Yoda which no one seems to have noticed. I'm almost positive that the shots of him are animation from AotC, NOT new stuff. It looks like it's been either recomposited with a RotS background, or, less likely, re-rendered entirely using the exisitng animation. My guess would be that what we are seeing is Lucas wanting to get some dynamic Yoda action into the teaser, without giving anything important away, and dealing with the fact that all of his good performance animation is most likely not finished (which, for a little animation lesson for some of you means no cloth or hair simulation yet...that will be done once they lock in the performance

). If you recall, Yoda's acting shots were one of the last things that ILM was able to nail to Lucas' liking on AotC. Anyways, just my 2 cents...

And, oh yeah, man is that EVER JEJ as Vader. I was actually leaning away from it being him, especially since there was just a little interview posted with him about not having recorded anything for the film yet....but listen to it through headphones, and that's aboslutely him.
