Will PS3 eventually pass 360?

PS3 wins last week by 10k sales, lets assume PS3 outsells X360 every week by 10k on average.

Based on PS3 outselling X360 by 10k units a week. It will take 810 weeks for PS3 to overtake XBox 360 or around 16 years.

So PS3 overtakes XBox 360 in 2025.

I don't see what the problem is, didn't Sony state that the PS3 is "future proof" and will last for 100 years?
