Those were mostly improvements on past CoD mechanics though. I think he meant CoD4 to be the one to introduce brand new elements to the FPS genre. I'm not saying BO2 didn't innovate (fave CoD thus far), but it didn't do anything ground breaking in the industry. Pick ten is a modified CaC, Scorestreaks are modified Pointstreaks (which are modified Killstreaks), many FPS/RPGs already have those, I really see how new zombie maps, characters and bosses are a major innovation in the industry, and L4D2 already had that zombie ability before. It innovates the CoD franchise, but not the genre, as CoD4 did. Then again, not every new game out there is going to be a "CoD4, Halo 3, or Half-life".
