Team Meat reported yesterday via their official Twitter account that Super Meat Boy sales have passed 400,000 units.  The Steam version actually outsold the Xbox Live Arcade version, despite the XBLA game coming out over a month prior.  Team Meat stated that the sales ratio is nearly even; “its like 55% Steam 45% XBLA” they stated.  Also of note in their recent postmortem was the upcoming retail release for the PC, and the announcement that they have become developers for the Nintendo 3DS, hinting that Super Meat Boy may go handheld.  The programmers also vented their frustration and difficulties with the development of the game during the postmortem.
