It's just too unlikely IMO.
For it to happen it would need next gen to start no earlier than xmas 2013 (likely anyway). Even so ...
(shipped)
2010 - 52 mill (roughly)
2011 - (15) - 67 mill
2012 - (12) - 79 mill
2013 - (9) - 88 mill
2014 - (5) - 93 mill
2015 - (2) - 95 mill
That is pretty much best case scenario, unless a Kinect AND 360 price cut really spur sales beyond belief and a $99 360 has a big legacy in the states.
It has an outside chance but I think 85 mill is a better target.
