these numbers kind of tell the whole story here.
There is no way that the 360 nearly outsold the PS2 (best selling console in history) in addition to the competition it got from the PS3 and even the Wii.
The "growth" we would have had to see that generation, certainly didn't carry over to the next generation, nor are those numbers represented elsewhere.
Microsoft gave a 3 year warranty from time of purchase in 2007 and the numbers started to spike up in 2010 and 2011 when people had to do out of warranty replacements.
Again, not a single Kinect game in the top selling lists outside of the bundled games, so Kinect was not this feature that drove the sales.
