I agree with Sgt.Safe-Sex. A CoD game that took longer to be released builds anticipation about it, and would make for more sales. Games that take more than a year to be released(Gran Turismo series for example) are MUCH better than games that are released that year after(like Need For Speed, though the new one looks awesome)
