Then that must mean that World at War is in the same timeline as MW because of BO being a somewhat continuation of Reznov's story and Miller (from the WAW American campaign) being hinted at in the BO campaign. And you could also go back and say that the Price from the original Call of Duty is a relative to John Price of the MW series.
