There are three new TV spots over at Ye Olde Official Site(TM).
Teaser is a greatly shortened version of the original teaser trailer.
Dark Side Unleashed is a montage of images from the existing trailers, maybe with a new shot or two.
Tragedy is especially good and has a few great lines not in the previous trailers.
A few more minor spoilers a la the sort in the longer trailers, but no real giveaways.
Man, this movie is going to rock!
