Have you had a chance to watch the new Iron Man 2 trailer yet? It aired after the Oscars (and danhimself even posted it on the forums here). I do think that it's literally time to start counting down the days until this movie comes out.
This movie looks so good. There's not much else to say. This is just the beginning. After Iron Man 2 we'll have Thor on May 20, 20111, The First Avenger: Captain America on July 22, 2011 and The Avengers on May 4, 2012.
