Microsoft's first CES 2012 stat is in and it's good news for Kinect. The software giant has shifted 18 million Kinect sensors in total, alongside 66 million Xbox 360 consoles, making it the best selling console in the US during 2011. Microsoft's Xbox LIVE service is up to nearly 40 million members, and momentum for the company's Xbox products doesn't appear to be slowing down. After selling 1.7 million Xbox 360 units in a record breaking November, it's no surprise that Microsoft is proud of its Xbox growth.
