Today Microsoft announced the price, release date, and even the name of their newest peripheral for the 360. This peripheral is, simply put, a small keyboard. It attaches to the bottom your Xbox 360 controller, wired or wireless does not matter, and allows you to text chat with your friends (sidekick style) on XBL without having a large keyboard. It’s being released September 4 for $29.99 US under the name “Xbox 360 Messenger Kit”. The set also features a wired headset as a bonus, but no pictures have been posted of the headset.
