While it looks awesome, it keeps with tradition by giving too much away.
Remember this scene from Iron Man 2?
It was featured in all the trailers. And because it was, there was no tension in that scene when we actually got to see the movie. When the fight starts, we're not thinking "oh no, how's Tony going to get out of this!?" We're thinking "hey, we're almost to that part I already saw on tv a dozen times yesterday!" Credit to this new trailer for not spoiling the same things as the Super Bowl teaser, but between the two, it's easy to see how some parts of the movie are going to play out.
Iron Man 3 opens May 3, which means it'll be followed by Free Comic Book Day - always the first Saturday in May. So go see IM3, then come in and get some free books and donate to Martin Memorial Library at the same time.
And if you want to read the comics that inspired the new movie, come in and ask for the "Extremis" tpb. It's great!
