I did up two charts to try to better see the state of things. The first is a circular graph. Note that December of one year connects to January of that same year, not the next year as it probably should. Just an artifact of the software.
2008 was as much an outlier year as 2009 was in the other direction. 2010 starts out following the average line, but at the end we have a counter cyclic trend line, which if it holds up will make December an unusually active month for sales, comparable to 2009's numbers. I'm as big a bear as they come, but for those trying to get out of this market, there may still be time. (Especially with an 8 in the address.)
