Change is in the air for Marvel Studios and their upcoming film properties. Today the studio announced that they are pushing back some of their most anticipated films in an attempt to have a more cohesive set up to the Avengers team up movie. Along with their date changes, Sony also announced that Spiderman 4 will be released on May 6, 2011. Check out how this shuffle will effect Thor, Iron Man 2, and Captain America after the jump.

According to ComingSoon, a Marvel based film will dominate the summer blockbuster season for the next three years. This will be the first time that such characters and films have been interwoven to launch a big screen collaboration.

“This new schedule strongly sequences Marvel’s movie debut dates, big screen character introductions and momentum. It maximizes the visibility of our single character-focused films, leading to the highly anticipated release of the multi-character ‘The Avengers’ film in 2012,” said David Maisel, Chairman, Marvel Studios.

Below are the new dates for the Marvel films that will be released between 2010 – 2012.

Iron Man 2 remains set for May 7, 2010, while Thor has been pushed back  from July 16, 2010 to June 17,2011. The First Avenger: Captain America has gone from May 6, 2011 to July 22, 2011, and The Avengers will debut on May 4, 2012 as opposed to July 15, 2011.

As you may have noticed Thor and The Avengers have gotten pushed back a year, which I think is a smart on Marvel’s part. Thor is the most mystical out of all the characters, so his story may be the hardest to root in reality. I’m also relieved that they put some breathing room between The Avengers, and it’s predecessors to allow some time for proper story development. No one wants to see a rushed team up movie. No one wants to see a rushed movie period! They’re horrible to watch (X3).

I’ll admit that the wait will be excruciating, but the final result will make up for it. On an eerie note, will anyone else notice that Robert Downey, Jr. and Don Cheadle will be almost 50 years old when The Avengers finally debuts?

What do you think of Marvel’s new slate? Is this a smart decision on their part?
