Just curious, what is the evidence for the 2012 reversal?

The poles have been moving rather fast recently (the last few decades) but we only have data from the last 500years of where they were so it's hard to tell if this is typical before a shift.
Shifts seem to occur every 100,000 - 10,000,000. We are a little overdue a switch based on the geological record, but the changes aren't regular like an astronomical event, they are more chaotic.
