"So, the rumors are already beginning to ring true; another Modern Warfare title is coming. I can’t say I’m surprised, given how well the franchise continues to sell, with each entry in the series repeatedly breaking the sales record established by the last.
Nobody can deny that the franchise has already become stale in recent years, but I also think I can speak for many when I say that Black Ops II has breathed some new life into the series, and it has introduced gameplay and storytelling elements that can be expanded upon in future installments.
With that said, here are five things that whoever’s in charge of Modern Warfare 4, be it Neversoft, Infinity Ward, Raven, or whoever, should keep in mind when creating the game so that they continue the innovation that Black Ops II has sparked and keep the franchise fresh."
