Call of Duty will sell more on PS4.

[eFKac]

Ghosts at least I think will sell better on the Xbone in US, but unlike Halo for example, CoD is not only a US phenomenon, Europe should put the PS4 version ahead overall.
Next installments, it depends. If PS4 goes as strong as it has the potential to, I can see it being the strongest CoD platform in all regions.
Still of course Ghosts and possibly the next Treyarch one will still sell the best on the 360.
