Who knows how long this will stay up, but The Pursuitist has a (non-embed) copy of the Thor reel that was shown at Comic-Con up. So go watch it already HERE: http://pursuitist.com/arts/thor-comic-con-trailer-watch/
Looks pretty damn good if you ask me. The way it's cut looks a lot like what the first "real" trailers will probably look like: A "story" trailer with lots of fanservice in the margins. It's not quite the "holy shit!" of the first Iron Man trailer, but we do get to see how everyone "looks" under proper lighting and post-production, all the main guys in full armor and helmets, how the hammer fighting/throwing is being staged, what the basic story is (Thor depowered and busted-down to Earth, has to prove himself as a hero so he can get his hammer and powers back), how/where it "fits together" with Iron Man 2 and how Destroyer looks in motion. With a few moments snipped for time, this could (and SHOULD) be playing in theaters now.
