But also Damac raises a point in stating that Foley is a secondary character. A reference to him would seem a bit out of place. Especially since Foley is a Modern Warfare 2 character, which Sledgehammer had no input into making. Granted they might slip in an Easter Egg to MW3, but aside from that, I don't see any EEs to any other games.
