Yet another retailer has listed the Kinect add-on for the Xbox 360 at a price of $149.99, but this time, it's a little different: the price is on Microsoft's own site. Over on the Microsoft Store, the "Kinect Sensor for Xbox 360" is clearly listed (and available for preorder on November 4) at $149.99. We've screencapped the image above, just in case it gets removed in the future.
Of course, this still doesn't confirm the price for certain -- the retail side may have no more inside information from the company than any other retailer does, and may be simply listing what it expects the price to be. Or, the price may have gone live early accidentally, pending an official announcement. Either way, throw another piece of evidence on the pile for a $149.99 price on Microsoft's controller-free gaming system.
