The minimal PS3/360 gap will be 3.5M and maximal 5.5M by the end of 2009

Weekly PS3 sales > weekly 360 sales

Aligned launch PS3 sales > aligned launch 360 sales every year from launch

Hence PS3 wins. See, simple maths.

(or PS2 wins if you don't take aligned launches, which doesn't make sense)

Feel free to discuss or spin facts. Nice Halo 2006 avatar though.
