The reason for all the hoopla about 2012, is that in the Maya Calendar, the last creation ended on a 13th Baktun. The lunatics suppose that since the last creation ended on a 13th Baktun, the Maya supposed that this creation would also end after 13 Baktuns, but there is no evidence that the Maya had any such beliefs. There is a date on the West Panel of the Temple of Inscriptions from Palenque that refers to an anniversary of the crowning of the king, Pacal, that makes it quite obvious that the Maya believed that there was a 14th through 20th Baktun.
So, in summary, these guys are wrong about the new correlation, and all the 2012 nutjobs are wrong about even the Maya believing that 2012 was the end of this creation.
