"Microsoft is pretty positive about the Xbox 360s showing in December, calling it "the biggest month for Xbox 360 in history." The company boasts outselling its Sony competition two-to-one for the holiday quarter. Mmmm... selective!

But let "em gloat, we say. While the Xbox 360 didn"t quite double sales of the PlayStation 3 last month, it came close enough to easily justify a "nearly." It also saw Xbox 360"s "weekly sales run rate" increase 38% over November, which I"m sure is a very important milestone for people who measure weekly sales run rates.

Perhaps the choicest self-congratulation from Microsoft"s response is that the 360 "generated more life-to-date dollars at retail for third-party publishers than the PS3 and Wii combined" to the tune of a half-billion dollars. Champagne all around!"
