Back to topic: It’s been confirmed that XBOX360 will be stuck using controllers but PS3 will have Move, keyboard/mouse, and controller support and PC/Mac will have cross-platform matchmaking with PS3 users. I’m actually looking forward to that, opens the door for a highly competitive PC vs console exhibition match at LANs

Also the article states the game won’t be coming to XBOX.
The article you linked said it would be coming to XBOX but that Steamworks wouldn’t be implemented on XBL.
Personally, I don’t think it’s even possible to implement Steamworks on XBL. PSN was pretty basic in terms of coding which made it trivial to simply overlay Steamworks on top of it as an addon. XBL has a pretty complex backend framework and I don’t imagine MS would be too keen on releasing all the code for that to Steam for them to make the modifications. I don’t think it’s fair to bash MS over it, XBL is twice as old as PSN and those extra years do a number on the flexibility of the system. If PSN was 10 years old I imagine it’d be in the same boat. Then again, if PSN was released in tandem with XBL it would probably have forced XBL to be a free service <_>
