Yes, there MAY be an America's Best Dance Crew Season 6!

According to District 78's Twitter, America's Best Dance Crew will be coming back in 2011: "It's so hot, how about some good news. #ABDC6 Is going to happen. 2011 and hopefully with nicer weather".
UPDATE: They've retweeted saying that they have no definite information.

This corresponds to several rumors I had heard about auditions in late 2010. If you've got other news, leave it in the comments.   And thanks for the tip, DirtfaceX and Jon!
