Why dont you compare the ps3 and wii software ratios? Im more than certain the ps3 has a higher attach ratio. Also how can you expect the ps2 to have a 40% attatch ratio if it sold 130million, and only a couple of games surpassed the 10 million mark whcih isnt even a 10% attach ratio.
PS3 vs wii
2008 end of year predictions:
PS3: 22M
360: 25M
wii: 40M
