Bloomberg News reporter Dina Bass took to Twitter to deliver a confidant recalculation from Xbox's top dude, Don Mattrick. Microsoft revised its Christmas season Kinect sales forecast from 3 million to 5 million which, according to Bass, Mattrick says "would make Kinect the biggest Xbox product launch ever in terms of sales."

It would also dwarf the Xbox 360's 2005 holiday launch in which it sold 1.5 million units worldwide from November 22nd through December 31. Not impressed? It's also considerably more than the PlayStation 3's worldwide sales figures of 1.7 million units just one year later. Last, and perhaps more telling, is that the newly revised estimate also trumps the Wii's relatively impressive 3.19 million units sold worldwide during its first holiday season.

For an accessory, 5 million is a pretty staggering number for just a few short months on shelves. That is, if Microsoft can keep it on shelves and meet demand. Each one of the aforementioned consoles was met with severe holiday season shortages; to come out on top of this numbers game, it would seem that all Kinect has to do is be available.
