I don't think anyone would expect them to magically remove any and all latency problems from the games, but it is fairly clear that players with great pings are experiencing latency problems, which shouldn't be happening. With MW2 back, there weren't many problems with latency; a player with a great ping and a fast isp would have little to no problems. After that, BO forward (And as some players have told me, MW2 included), discrepencies between killcams and client side have been on the rise. Players complaining about seeing themselves not firing a shot during a killcam, when on their end they had emptied an entire mag. These discrepencies have became increasingly prevalent, and with the release of BO2, it's observable almost every time. I've heard theories blaming Theater Mode for this phenomenon, but anything could be the culprit.

This isn't happening to everyone, but it does happen, and is a serious problem, especially in a heavily twitch based multiplayer shooter.
