@Polarimetric,
You do realize that the 360 will be price adjusted in 2010. There is no avoiding this and that like the 360 price adjustment in 2008 and the PS3 price adjustment in 2009 will have signifigant impact. People that believe the 360 will just start slowing down and dwindle to next to nothing in the next 2-3 years assume the 360 has hit the lowest price point it will hit.
As for comparing to other generations the comparison cant be made. This generation will be the first generation with 3 consoles over 50 million. The assumption that because MS will end the 360 life early because the Xbox ended after 4 years make a poor assumption. They have not looked into why MS ended the 360 early. This generation is far from over. With MS making the big investment of Natal is a total tell that MS has no plans for a new Xbox in 2011 and maybe not even 2012.
Its libraries that sell systems not a single game.
