Think about it: If the current game is anything to go by, we might as well let the Xbox boys find all the glitches and bugs. The amount of time before PS3 and PC get the DLC, and the amount of time it would take to fix the DLC problems if it came out for those consoles at the same time is probably the same. Either way it's unplayable. Of course, there's bound to be a handful of problems when the DLC gets released on other problems, but at least most of the REALLY bad ones will be sorted out.

There's already an active thread for discussing the DLC: http://www.gamesas.com/index.php?/topic/1143163-first-dlc-announced/
