With each year the PS3 version of Call of Duty has taken up a bigger share of the games HD sales, going by the previous games

Call of Duty 4 sales = 14.46 million sales gap = 2.58 million

PS3 share = 41% 

World at War sales = 11.33 million sales gap = 1.87 million

PS3 Share = 42%

Modern Warfare 2 sales = 22.21 million sales gap = 2.93 million

PS3 share = 43.5%

Black Ops sales = 24.20 million sales gap = 2.02 million

PS3 share = 46%

So as you can see there it was Black Ops that gave the PS3 a big boost share wise, mainly thanks to the PS3 comfortably outselling the Xbox version in EMEAA (it was still pretty even with MW2.) Also it was inbetween MW2 and Black Ops where the PS3 finally surpassed Xbox 360 in EMEAA.

When Black Ops was released the sales gap worldwide between PS3 and Xbox was 3.5 million by the time MW3 is out that gap will be around 2.5 million and EMEAA is now soundly ahead of the Xbox.

I dont think Modern Warfare 3 will sell more on PS3 than Xbox, but I do think the gap between the two versions will decrease even more as the gap in EMEAA will continue to grow.

But the year after that when Black Ops 2 is released (not the actual name) PS3 should be ahead of the Xbox worldwide and then it may be possible for a Call of Duty game to sell the most copies on PS3.

Do you think itll ever happen? And if you do then when with MW3? Treyarcs next game? MW4?

Never, maybe it can increase 1-2 % again with MW3 and next year Cod.

COD has sold more on the PS3 every year for the past few iterations.

MW3 > BO > MW2 > WaW

when they make a CoD thats about killing US americans, which would then be banned in USA

If/When the Xbox brand dies.

I dunno if id say never, i think its possible. MW2 sold 35% more copies on Xbox than the PS3, but Black Ops on the Xbox only sold 22% more copies than the PS3 version.

Thats a huge amount less, and that percentage will only continue to drop as Black Ops has been selling better on PS3 for weeks now, its had better legs so far.

This time next year i bet that the gap between the PS3 and Xbox 360 version of MW3 is less than 2 million.

Next year gap will narrow since PS3 will get huge boost at 199$.

cud do more next gen if PS4 and 720 are launched together

though still MS could block it by exclusivity agreement

never

probably when hell freezes over
