Research firm NPD has released some numbers for January that shows that the gaming industry isn't doing quite as well as it was a year ago, down 38 percent in both the hardware and software categories. The major cause for the drop was that January 2011 was actually a banner month for new game released, while January 2012 was quiet by comparison. That said, Microsoft is still pretty happy with the results as it says the Xbox 360 got its 13th-straight month of leading game console sales. The company says it won the top sales spot for all of 2011 thanks to the Kinect and its attempt to re-imagine the Xbox as an entertainment hub, both of which helped alter and widen the traditional bell-curve graph you typically see over the life cycle of a gaming console. The console's longevity should help bridge the gap to its replacement, which isn't going to be released this year.
