User blog comment:Crazy sam10/Infinity Ward explains leaving Modern Warfare series/@comment-71.57.202.60-20130601160113/@comment-6565193-20130603194650

They're leaving the series as in Story arc.

Think of it as this. Modern warfare is Family guy and Ghosts is American dad. And Black ops/World at war is the cleveland show. Make sense to you? If not then you are one dense mofo.
