I think a 10 year lifespan is pretty reasonable given the length this generation is supposed to have.
The PS3 isn't going anywhere any time soon, regardless of what people hope. Sony has made a huge investment into it and I doubt they will just turn their back on it. Yes, they have lost a ton of money so far. But, there is a lot of time left in the game and all the more reason to try and earn their money back (mostly likely through software and hardware adjustments).
The PS3 will be fine, it isn't selling the best right now, but give it time.
