Microsoft's CES 2012 keynote did let slip one juicy morsel of news: Kinect will be coming to Windows in February 2012



From Techradar:

Starting next month, Windows users will be able to control their PCs and laptops by motion and gestures, with nary a mouse in sight.As well as allowing you to control things on screen your computer will know broader motions too, like when you're sitting in front of it - so it could feasibly put itself to sleep when you get up to make a cup of tea, then bring itself back when you return.
