I don't know about the us but in the uk the xbox 360 has a far wider and larger range of games and the xbox 360 is far outselling the ps3.In the uk we now get 3 years warranty on a new xbox which if i was buying a console would sway me towards the 360 .One of my workmates bought a ps3 and tried to get his money back the following day but because he opened the box they would only offer him 200 pound so he is keeping it, I am not sure why he wanted to get his money back but it could be because he likes driving games and not shoot em ups or fps style games .More choice on the games front might be better for your son though I am not an expert on consoles i like my pc .
