I saw where they were releasing it in black too, might have been on Gamespot or Aeropause I can't remember. Anyway, even if they don't, you can make it black with spray paint
I just bought a cheap USB keyboard for 7.95USD earlier today to use on my 360. I love the messenger integration but typing on the controller absolutely sucks. If the Chatpad is 20USD or less I'll probably get one, otherwise I'll just stick to the USB keyboard.
