Activision gave some oxygen to Call of Duty introducing development cycles of 3 years per title. Advanced Warfare will be the first product that will benefit of this new policy. One way or another, we are going to have one new Call of Duty every year, one after the other.
The next year should be the turn of Treyarch and probably they will continue the Black Ops saga. That’s the logical step, but reportedly this box-art has appeared as a placeholder on Amazon:
World at War 2? Part of the crown consider the first iteration one of the best Call of Duty games, so, in some way Treyarch could please their fans with this unexpected development.
Just to remark, it’s strange to see a placeholder of World at War 2, it’d be so much time before the official release (2015). Therefore, it could be feasible that this picture was a fake.
