According to VGChartz software numbers, The xbox 360 has an attatch ratio of around 7.5, while the PS3 has an attatch ratio of around 6 (with the xbox sporting one extra year of life).
Disregarding inaccuracies in the VGChartz total software figures, this shows that Peter Dille is cherry picking to suit his argument.
Indeed, I would say his figures points to the Xbox 360 having a stronger game library overall, because Xbox 360 owners distribute their purchases over more games than PS3 owners do.
