User blog comment:Ausir/It takes 500 people to make Call of Duty/@comment-124.184.224.25-20110909115600

This "500" figure is simply a marketing ploy essentially. It is remarked in the source article that 500 people work on the "series", not the one game. Knowing this, you realise that there's not a 500 strong team behind MW3, there's probably about 180-220 once you take away things like companies doing the PORTS, the next major game being developed (it's happening now, always has with CoD) and things like marketing (jobs unrelated to the physical development of CoD games).
