Kinect worldwide sales at 8 million after only 60 days [Updated]

Speaking during Microsoft's CES 2011 keynote, Steve Ballmer started off strong with some good old-fashioned number-centric chest-thumping.

Specifically, he announced that Kinect's already moved 8 million units worldwide. Yowza.

For comparison's sake, the all-seeing camera was only at 2.5 million in November. Looks like Microsoft had quite the merry Christmas.

Ballmer did not, however, specify whether he was referring to units sold to customers or shipped to retail. We'll mail Microsoft for clarification.

Update: Microsoft informed Bloomberg reporter Dina Bass that the numbers do, in fact, pertain to retail shipments. However, Microsoft also added that it's "far surpassed" 5 million sold, but wouldn't elaborate any further.
