I think Sony should analyse the past generations a little bit better before making such announcements. If a console fails saleswise in its first two or three years, it has no chance to come back anymore. So in my eyes, a ten-year lifecycle for the ps3 is suicide if sales don't start to improve very soon.
Just imagine Nintendo would have stuck with the Gamecube for another five years, saying that it doesn't matter they didn't sell that much in the first years because the Cube will be around for a longer time than it's contrahents. This doesn't work. An uncool console won't become cool just because it does not get a successor. In five years, Nintendo will most likely release a Wii 2 with at least PS3 comparable graphics and Microsoft (if they stay in the gaming industry) will launch something new that is superior to the PS3. So if PS3 wasn't able to beat Wii and X360, how will it beat their successors?
Of course I'm assuming that PS3 loses this generation, a ten-year lifecycle might be possible for a winning console like PS2.
