According to Eric Wareheim's Twitter [@ericwareheim], Season 5 is due to air in March 2010!
No specific details were given; fans who attended the Tim & Eric event over the summer in New York City were treated to a few sneak-peeks at the new season. These clips were met with applause from the crowd. (Unfortunately, we were sworn to secrecy, so no spoilers!)
What has been said about the new season however, is that it's the darkest and most disgusting season yet! It's also rumored to be the final season of Awesome Show, but that remains to be confirmed or denied.
