What he (the anon) means is it takes each CoD game two years to be made Ctrl+C'd and Ctrl-V'd onto a new disk. But I think the idea is that a good game needs more than a year between releases for the devs to look over the outcome of the game, and then actually implementing the findings in the new game before the "code freeze". CoD devs look at the previous installment, analyse what they find and do sod all.
