Treyarch releases a game every other year because they are always working on a game and that is how long it takes including time spend on the add ons and other after market activities like fixing glitches and other needed updates. Not everyone works doing the same things at the same time. Some were still working on Black Ops while others were working on Black Ops II. It is not a him it is a company with a few hundred employees
