The twelvers, like Ahmadinejad of Iran, believe 2012 is the year for total chaos on Earth (the Earth to them is not the sphere as we know it) prompting the reurn of the Mahdi who will punish all of us infidels to no end. Sorta coincides with the Mayan calendar? Of course, if they are wrong, then they can still be twelvers and just start thinking of 3012 instead. Now, if the Mayans are correct, think of the good side: Obama won't be re-inaugurated in January...unless HE is the Mahdi!
