The gap between PS3 and 360 sales of COD games has been decreasing year over year.Black Ops sales of both the platforms are separated by just around 2m
The gap may decrease further this year following pricecuts of PS3 which is still way overpriced compared to 360
Along with this NGP releasing this year and COD coming to it.
Now we know there will never be a cross platform play between 360 and PS3,atleast in the near future
But here comes NGP which is a Playstation family device and as devs have said how easy it is to port a game and as both NGP and PS3 will use the same gaming network aka PSN which would bring crossplatform gaming.
The combined sales of Modern Warfare 3 on NGP and PS3 could surpass 360
