Nothing
If you want a legitimate answer to this question, nothing is really going to happen.
Like someone else said, the mayan calendar rolls over, just like ours does at the end of every year. The planets are not aligning, and there is no way to predict polar shift, so that is also almost definitely not happening.
There will be a transit of Venus around June 5-6 of 2012, meaning that Venus will pass between the earth and sun, blotting a small spot out. If you want to see it you can make one of those pinhole cameras to view the sun without burning your retinas beyond repair. This is actually a very rare occurrence, and won't happen again in our lifetimes.
Sorry, the planets aren't aligning, the poles are not being magnetically reversed, and the world is not ending.
