There's a huge gap in America. but in "Others" The PS3 versions sell more with a smaller Gap. No need to say anything about Japan.
For me: As long as the PS3's userbase isn't ignored am good. And am sure more games will be charting on the global figures [don't think NPD does global] for PS3 when the "others" userbase favors the ps3 more in terms of numbers..... If SONY can get the HW numbers Higher... that 360 price cut did wonders.....
