After the success of Call of Duty: Modern Warfare, developed by Infinity Ward the godfathers of the series, it's hard for this guys to bring again a 9 - 10 rating product like the previous one. But from what I've seen at GC Leipzig, this game will bring another huge portion of WWII in our homes with a lot of cinematics rated M.
Definitely the M rating opened new doors for the developers in terms of story and action. One part of a level called "Makin Raid" shows a cinematic where an allied soldier is tortured by the Japanese, before having his throat cut by a katana. Such dramatic images would have never had the chance to appear in Call of Duty without the acceptance of Activision to bring the new installment for mature audience."
