What the hell is Da Vinci's Armageddon?

So suddenly Da Vinci has an end date for when the world will end, joining the Myans???? I think when 2012 is over, Da Vinci's Armageddon will be the new date set for the end of the world and people will make money out of it like they did to deceive us about 2012. Who's next Dalai Lama????
