To be fair, sales between the PS3 and 360 worldwide are virtually equal. It doesn't get mentioned much since the internet is so US-dominated, but Sony and MS are evenly matched right now. What will happen between them in the future is anyone's guess, as is whether the Wii U and 3DS will be as successful for Nintendo as the Wii and DS have been.
