Sounds like a crock to me. The game is already segregated by chat capabilities and there isn't even chat in the game. And as far as bandwidth goes, it's not going to take up much sever speed. A chat with 8 people is going to take around 100-200 kbps. I think the problem is that they don't know how to implement voice chat in the game or they don't know how to get around an in game cross platform chat system. They talk like everyone playing on one server is going to be in the same chat. Eight people talking in a group isn't a big deal. I do it all the time playing games like COD or Battlefield.
