What stage of its life is the Xbox 360 in?

[Kenryoku_Maxis]

If you were looking at the 360 just at face value, based on its price, the exclusives its gotten, its 'hype' meter and its age, you could easily say its past its halfway mark or even past its prime. But considering this 'gen' is anything but ordinary and both MS and Sony have stated they wanted their consoles to last as long as possible (even rumoring into 2014 if possible), then these views might just be from looking at past gens as a limited measuring stick.
