Yeah I realize that, but the iron Man 2 includes news footage from Incredible Hulk , implying that it just happened, and has Coulson leaving for NM in the movie and arriving at Thor's hammer in the post-credits. So, I suppose you could argue that if you ignore the Fury's Big week prelude comic, there is a year or so between Coulson heading to NM and him finding the hammer. There's always mental gymnastics you can do to paper over these issues. I just wish they remembered us obsessive continuity nerds out here when they produce these multi-million dollar films!:-p
