IW is dead.There aren't on PC, and that's the only downfall to the game...other than toobers who think they've got skill from it =P
But with Black Ops on PC they have their servers set up like CS used to be, which I like and pretty sure that Infinity Ward is going to implement that type of "game finding" in the next MW.
EDIT: I'm surprised this hasn't come up yet but also anxiously awaiting D3's release.
