Well, this is sort of a bummer. It seems we're going to have to wait a while longer for Marvel's Thor and Avengers movies, as they've been pushed back a year each:
Not mentioned in that list is that Spider-Man 4 is also slated for May 2011. In other words, there are three Marvel movies scheduled for three consecutive months in 2011, and just one scheduled for 2010.
I guess it's probably a good thing that the movies were pushed back, seeing as we haven't heard anything definitive yet about any of them aside from Iron Man 2. I just worry that if one of the 2011 releases isn't that great, the others will get lumped in with its bad press. Still, at least Marvel is keeping their timeframe on the realistic side, and I hope the movies will turn out for the better as a result.
