Microsoft sent out a little email of jubilation this evening touting sales figures for the Xbox 360 and a few of its published titles. Microsoft states it has sold 17.7 million Xbox 360 consoles worldwide and although the NPD numbers aren't out yet for December, the Xbox 360 sales should be higher than the 770K sold in November. Not including the data from December, Microsoft says it currently has a hardware to software ratio of 6.9; that's a .3 increase since we last checked all the consoles in October.

Speaking of software, "teh Haloz" was sold 8.1 million copies since launching Sept. 25 and it appears the statistic that around 50% of Xbox 360 owners have Halo 3 is not just a US number, but a global figure. In a great sign for fans of dramatic space operas, Mass Effect sold 1.6 million units since introducing us to interstellar pleasure Nov. 20 -- keep those Hanar tentacles crossed for a sequel announcement this year. The full NPD numbers will hit the streets on Jan. 17 to give us the full details of this very merry consumermas.
