The Mayans did not predict the end of the world in 2012. In fact, they predicted events much AFTER 2012.
Its just a tick over on the metaphorical oddometer. No more magical than the change from 1999 to 2000.
Scholars from various disciplines have dismissed the idea that a catastrophe will happen in 2012. Mainstream Mayanist scholars state that predictions of impending doom are not found in any of the existing classic Maya accounts, and that the idea that the Long Count calendar "ends" in 2012 misrepresents Maya history.[3][5] The modern Maya, on the whole, have not attached much significance to the date, and the classical sources on the subject are scarce and contradictory, suggesting that there was little if any universal agreement among them about what, if anything, the date might mean.[6]

Its seems, not even the real Mayans care about it - so why should we?
