Given that the Ps3's sales have repeatedly faced slowdown, there's absolutely no way this will happen.
But provided it can at least keep momentum, after ten years, it will sell - at the VERY BEST - just shy of 100m.
I took the average number of PS3's sold daily to date (~27,000) and figured out how many days there are left in a ten-year cycle. Multiplying that number by the ~27,000 number I'd calculated, then adding 34m (the PS3's current sell-through), I get 99,357,621.
Given that I didn't account for leap years, we can be generous and give that an extra two days sell-through, so you can tack on another generous amount of 56,000 to that. Still leaves it 597,000 units shy of 100m.
And this is assuming the next generation doesn't steal the attention, but instead people by the droves suddenly start thinking the PS3 is amazing and start buying like hotcakes.
Which is incredibly unlikely.
