The Kinect has appeared on the Microsoft online store and has been given a price of $149. It may come as something of a surprise given that company spokesperson Aaron Greenberg continually denied reports that had printed the specific figure.
The store listing is for pre-orders and informs potential buyers that for that price they get the Kinect sensor, a power cable, a Wi-Fi extension lead along with a detailed manual on how to calibrate it.
It also confirms that for best results you will need six foot of space between you and your TV. That, and the money of course.
