Microsoft is estimating that it will sell 5 million Kinect units by Christmas, a boost for PrimeSense, Marvell, TI, ST and the system's other component suppliers, UBM TechInsights said.

Kinect is Microsoft's initial foray into motion gaming, a category popularized and dominated by Nintendo Co.'s Wii. Sony Corp. also recently threw its hat into the ring with a $99 bundle for its PlayStation 3, Sony Move.
