From the “Oh… Ok?” department,
Joystiq got confirmation from Microsoft today that there is an 802.11n wireless adapter coming for your Xbox 360. No details on date or price were given and Microsoft only asks us to “stay tuned”. 802.11n is newest generation of 802.11 wireless tech and allows for faster wireless transfer speeds. In order to take advantage of it you would have to have an 802.11n router and other n devices.
