The Inquirer reports that Microsoft plans to expand Kinect to Windows PCs

WITH THE ONE YEAR ANNIVERSARY of the Kinect fast approaching, Microsoft has announced that it will release a commercial software developer kit (SDK) to enable its Xbox gaming motion sensor to work on Windows PCs next year.
Microsoft released a non-commercial SDK earlier this year, which led to a number of software developments for Windows, but this latest move will allow for a wider range of industries to use the Kinect system for profit.
