You don't understand though. It's a lot harder to work the coding and such on 360. It's not that they don't want to update. It's that they can't.
You have to give Valve credit for making MAC versions of most of their games. And then readying to apply Steamworks with PS3 with Portal 2.
The 360 though... is a much bigger problem.
Wait what?
How is the 360 a bigger problem? If anything I think the PS3 would be harder to update because valve couldn't even work with the PS3 coding for the Orange box. Thats why EA made the Orange box for PS3
