TRAILER #3: "Avengers: Age of Ultron"

I'm losing track of what actual trailer number this is- I could have sworn there already was a third trailer, but apparently that's this one, which means the last one must have been the second...oh whatever. This new one looks like the best one, at least it gives some new footage. Still not psyched for this though- I'll be seeing it, but I think I'm just superhero'd out. I mean, it can't be all that new- villain terrorizes the population, leading up to a climactic battle involving all the heroes, with a scattering of jokes and banter in between fight scenes, right? Did I miss anything?
