Actually, since the beginning of 2009, Yellowstone has been recording higher than normal activity, which has worried geologists that something is up. Perhaps not a full-out eruption like in the movie 2012, but some sort of activity that could push its way through.
TIME Magazine did an article on it at the start of the year...

Overall, Yellowstone is much more active than most people suspect. In fact, courtesy of the USGC (the U.S. Geological Survey), here is the activity from only last month ago...
