Gaming peripherals The Kinect last year sold more than Microsoft had previously expected

And more than its cheap Sony PlayStation Move (hereinafter referred to as "PS move"). IHS Isuppli said that Microsoft's early years of the Kinect's annual shipments target is more conservative, only 5 million units, but the final sales figures are far more than this goal. As of January 4 this year, the total volume of Kinect shipments reached 8 million units. By the end of 2010, the Kinect's global real shipments were in 6.36 million units, while Sony PS move shipped at 5.23 million units in the same period. Sony has taken three ways to market PS Move: one is retail separately, the other is the primary set of PS-move-bound cameras, and finally the binding PS3 host sales. IHS Isuppli predicts that as a PS3 can be used for multiple PS move, Sony's body-sensing peripherals are expected to drive 4.26 million PS3 shipments worldwide. But while the individual retail version of PS move is 100 dollars cheaper than Kinect, Sony's marketing investment pales in comparison to Microsoft's. Notably, PS move is one months ahead of the Kinect market.
