Get Kinect-ed! Hey, that was Walmart's words, not mine.
They've already set up a dedicated page for Microsoft's motion-sensing product at Walmart.com. You can go there to learn about the tech as well as pre-order it. They have the pre-order set at $199, but note that your order comes with your choice of one game and a $30 Walmart.com gift card.
