The campaign of each new CoD could possibly be getting shorter every year because Activision often rushes the developers, possibly because of impatient fans or to get more money ASAP. There could be other reasons, though. But I'm pretty sure their new cycle will help fix that. Another issue is the fact that a lot of people jump straight into the multiplayer without playing the campaign first. I met someone a few months ago who didn't know that you can double-jump because they never played the campaign. They also never bothered to read the manual (although, it is possible that they bought their copy pre-owned and the original owner lost the manual.)
