There's not much to talk about in COD4 anyway...it's not quite a team game.
You can form up with a few guys and own if you're coordinated, but for the most part, you're on your own and you'll be dead in a half minute anyway.
Play a TF2 game on PC and you'll hear people talking lightly the whole time.
...or singing apparently.

Bet with disolitude: Left4Dead will have a higher Metacritic rating than Project Origin, 3 months after the second game's release. (hasn't been 3 months but it looks like I won :-p )
