What is said to be prophesied about 2012?

The Bible, the Mayans, Nostradamus and I say nothing about 2012. It is just some recent charlatans who say the End is then, and they lied about what earlier people said. 1999 was the original date, and when nothing happened then, it was changed to 2003, and again nothing happened, so it was changed to 2012. When nothing happens then, it will be changed to 2016-2020 in all probability. I KNOW silly hoaxes cannot possibly predict anything, so 2012 will be merely another year.
