wii 50million
ps3 40million
xbox 25million

the 360 is non existent in japan and ps3 rocks harder than 360 in europe ,the only place where 360 has a solid base is the US

Isn't the 360 outselling the PS3 in Europe as a whole and has a larger installed base there?

only thanks to the UK which is the same as US but 30miles from mainland europe
