The newest Avenger's Trailer is out. It's around 2 minutes of goodness:
That's pretty cool, I would say. I'm still not sure what the alien threat is, but this trailer is doing a good job making us interested in the movie. It shows a big threat, inner-team conflict, spotlights almost all of the team that makes up that conflict, has some cool action bits, a smidgen of humor, and of course lots of things explode. I'm excited for the premiere and hope this is really, really, good.
