10 year life span wont be decided by Sony PR and their fanboys, Sony must arleady be working on PS4, and the Developers with new microsoft console around 2011 will want to publish multiplat titles, and we know how hard is to port from 360 to PS3. If suddenly PS3 was to repeat PS2 success (whih wont happen believe me) then maybe yeah. A the moment the only console in this generation that has potential to last longer is wii, why? because many Wii owners (so called casuals) will be happy playing games as they are at the moment, because they look good enough to enjoy.
And with wii dominating this generation , Ninty will support it longer.
Sony needs to pick up in numbers big time, if they think about that 10 year plan, and trust me 5 year, 10 year plans wont work it has been proved, Communism was an epic fail
