Whoopsy daisy! US retailer GameStop has whacked up pre-order offers for Kinect and various Kinect games, revealing that it intends to charge $149.99 for the add-on.
While its standalone Kinect for Xbox 360 listing carries that price tag, a separate "Kinect Arcade Bundle" - perhaps meaning an Xbox 360 and Kinect, or perhaps meaning a software package - is listed for $299.99.
There's also a "Kinect Elite Bundle" for $399.99. Again though, details are scant.
Microsoft has not officially announced pricing for Kinect, although it has said that the add-on will launch in the US on 4th November and the rest of the world "thereafter".
