Gaming throat mic

Why are there no throat microphones designed for gamers? Well, actually, there is one, but with gaming peripherals being as much about image as functionality it is a bit surprising that companies such as Razer or Logitech don't carry a "military style" microphone for the hardcore FPS players. If I've spent a fortune on a 7.1 surround sound setup for my PC I don't want to put on a headset to speak to my CS/BF team, I just need a mic that can pick up my voice on the battlefield...
