Has Kinect failed gamers?

MMGN: It's been roughly one and a half years since Kinect launched worldwide in late 2010, selling over 8 million units in its first 60 days and making the Guiness World Book of Records for being the "fastest selling consumer electronics device" ever.

Since then, the motion-sensing device has sold over 18 million units as of January 2012.

It's safe to say from a financial and commercial standpoint, the device was a success as a product, and has no doubt helped prolong the life-span of the Xbox 360 and helped Microsoft sell millions more consoles.

But what else has Kinect notably accomplished or changed other than impressive sales? In my opinion, not much.
