This site explains what will be going on around the winter solstice in 2012. It's pretty long, but it's a good read. The Mayans were great astronomers, so it's possible that they knew about some of this stuff that will happen around this date.
As for me, I don't think it'll be the end of the world, but there will be a lot of cool stuff happening.
