How many current Call of Duty games took place in the "modern" era? Four (COD4, MW2, MW3, Ghosts)
How many current Call of Duty games took place mainly during World War II? Four *not including spin-offs or ports* (COD1, COD2, COD3, WaW)
How many current Call of Duty games took place in the future? One, with Advanced Warfare coming in November, making it two.
The future era is fairly unexplored territory. I would rather see more of that over another modern-based game.
