Originally announced for WiiWare and PC, Super Meat Boy will also be coming to XBLA, but here's the kicker: it's coming to XBLA before WiiWare and PC. Team Meat is hoping for a summer release with the WiiWare and PC releases coming shortly thereafter. There's no plan to bring the game to PSN even though Team Meat has told IGN it has the game running on a PS3 test kit (burn!).
The reason the developers are bringing it to XBLA is because it allows them to do more than on WiiWare. The game roughly halfway done so far, and it's already about 35MB in size. The problem is Nintendo limits the size of WiiWare games to 42MB, which means they have much more freedom on XBLA. That's one reason why the XBLA version will have online play.
