The only 2012 prophecies are the ones made by fringe writers to sell books
Sorry, that's just not true. Reminded of Yogi Bhajan and his thoughts about what would happen coming into the age of Aquarius, offhand. And he was far from a fringe profiteer. There are many more I could find with some basic research, that I can't recall offhand. The most vocal will always be fear-mongering people out to profit, but it's ignorant to call them the sole cause of the thoughts. They latched onto the idea, as happens with things like this.
Treat it like the day before, and the next. What will you do?
