Xbox One Kinect has been dated for a standalone release on PC, along with a rather steep price-tag.
Microsoft says of Kinect version two, “The Kinect for Windows v2 sensor gives developers more of the precision, responsiveness, and intuitive capabilities they need to develop interactive voice- and gesture-based applications for the Windows desktop and Windows Store. The v2 sensor is intended for use with the Kinect for Windows software development kit (SDK) 2.0.”
