If you want to look at the recent holiday season as "Round 1" of the motion controls battle between Microsoft and Sony, it would appear that Microsoft's Kinect is winning handily (bad pun, considering that it's "hands free" gaming). Not only has Kinect quickly shipped 8 million units, but for the month of December, Xbox 360 Kinect bundles outsold PS3 Move bundles considerably. The software for the motion camera is faring far better too, according to Wedbush analyst Michael Pachter.
"About one fifth of PS3 sales included bundles with Sony’s Move controller, suggesting a modest third month (we have chosen not to subscribe to peripheral data). About half of Xbox 360 sales included bundles with Microsoft’s Kinect peripheral, as Xbox 360 Kinect console bundles outsold PS3 Move console bundles by 5:1," Pachter said.
"Microsoft announced that it has shipped 8 million Kinect units since launch (in November), which was raised from its earlier goal of 5 million. More significantly, in our view, the top two selling Kinect software titles outsold the top two Move titles by over 13:1."
