I have some feeling that this year will see the biggest change to the series since 2007.

Activision pretty much knows by this point that if they don't innovate something, people will react neagatively, and they lose a part of their playerbase. Black Ops II last year proved the benefits of changing up the formula. MW3 had mixed opinions among the playerbase, while Black Ops II recieves little hate from people who played it.

With this, and heavy speculation of Microsoft and Sony's new consoles being announced (and released) this year, I think that this will be the year when Call of Duty makes another huge leap.
