2012: Zombie Apocalypse?

A zombie news site (!) has posted an article relating 2012 to a "Zombie Apocalypse". It seems that no matter what your favorite topic is, there is a way of connecting it to 2012...

Prophecies aside, how does 2012 relate to a zombie apocalypse? Certainly our world could be forever changed on this date by an unnoticed eschatological asteroid, disease or terrible quaking of the earth. The walking dead? Also plausible. Current scientific research into disease, reanimation and cellular regenesis is progressing as rapidly as other scientific disciplines.
