It really sucks when the best parts of the trailer are from a movie you've already seen. Can Lucas pull a rabbit out of his ass and make this one not suck? I'm seriously doubting it. However, some predictions:

• The Obi-Wan / Vader fight happens in a volcano which will lead to the Vader suit.
• Yoda has to kick someone's ass. Will it be Dooku on Dagobah?
• I will stand up during the movie to throw something at the screen in disgust.
