Episode III Trailer
There's a trailer for Revenge Of The Sith on starwars.com. It looks really good, but then again so did the trailers for the other 2 movies.
Hopefully this one's so action packed that there won't be any time for rolling-in-the-grass romance or Jar Jar Binks shenanigans.

Apparently George Lucas has turned into a whiny little bitch! I just learned that the trailer on starwars.com has been locked down, so unless you're a paying member of Hyperspace (which can be had for a mere $39.95), all the good content is denied.
