It was a PS2 series before switching to 360 for most of last gen but it's now officially (according to vgchartz) a playstation franchise again!
Call of Duty ghosts sales:
PS3 - 9.06M
Xbox 360 - 8.99M
PS4 - 2.67M
Xbox One - 2.03M
So Sony is winning the last gen and next gen COD battle and without the advertising or exclusive content!
So will Sony keep the majority of the COD crowd for Advanced Warfare? It's hard to see how it won't. PS4 has greatly increased it's lead since Ghosts released and will do so even more in 2015. PS3 has sold more than the 360 in the last year but that effect should be minimal.
Has the Kings last fort fallen or was that a once off blip?
EDIT: I just found out that Black Ops 2 was actually the first to sell more on PS3. SO the that was the turning point.
Black OPS 2 PS3 - 13.13M
Black Ops 2 360 - 13.10M
And now that the AW numbers are in the gap is widening big time.
AW PS3 - 2.05M
AW 360 - 1.78M
AW PS4 - 4.26M
AW X1 - 2.76M
With every new COD that comes out that gap will only get bigger.
