A bloody awesome trailer for Super Meat Boy (with some gameplay footage) was recently posted on IGN. Team Meat's upcoming WiiWare release should be out sometime in early 2010.

Note also that Edmund McMillen and William Good's Time Fcuk will be released on Newgrounds sometime later today. You can find a brand new trailer for the game in the extended.

[UPDATE: Time Fcuk is playable on Newgrounds now.]
