Madden on X360 will easily outsell Madden on PS3. All you Sony fans like to set yourselves up to big letdowns. Just admit that X360 is THE American sports console and you'll realize that yes, the PS3 will get closer, but the X360 will still win.
This is like someone claiming that PES will sell better on X360 because Microsoft payed for professional tournaments to use X360 as the console of choice and advertising exclusivity. It won't change that PS3 is the much stronger brand in Europe where soccer is incredibly popular
