i dont think it will. japan is not as big as US as a gaming market but it has no sales for xbox360 and US has few for PS3 but they have some... while PS3 will sell 50% of what XB sells in US, in japan XB will sell only 5 to 10% of PS3 numbers. EMEAA is more or less a tie! in raw numbers this give the advantage to XB but in my opinion will only get XB a shorter distance... not an overcome! i say more than half a million between them!
