Have you experienced some issues with playing Call of Duty 2 against your friends online? A patch is in the works to try to remedy the situation.
A post on Xbox.com says that they will concentrate on fixing the lag problems and other issues as well. I think it is great that Infinity Ward is taking a crack at patching a game, but in my mind console games should not have these problems when they leave the factory. That should only be a computer only issue.
