Microsoft announced a $399 bundle that include Kinect controller-free device with a new 250GB 360 slim and a copy of Kinect Adventures game. "With 250GB 360 model retailing at $300 and Kinect soon to be available for $150, the bundle offers up modest savings for those buying their first 360. It might also be a good option for those who've an older 360 model and are looking to upgrade. Of course, it's not the only option available, as Microsoft has already previously announced a 4GB 360/Kinect bundle for $299."
When Kinect launches later this year, a total of 15 games will be available, including Kinect Sports, Kinectimals, and Harmonix's Dance Central. If you don't feel like waiting for your motion controls, Sony's PlayStation Move will be available later this month.
