More Short Sales than Foreclosure Sales in September

I'm currently working with three short sale transactions (and about to add a fourth).  Clearly they are challenging for all parties involved but are a major factor in this market and with hard work and patience, can end in a successful sale.  I've been tracking the short sale & foreclosure market since January 2009.  Much has been made of the constriction of foreclosures in light of  'robo-sign' practices of processors and the number of transactions has been in flux, but I was surprised to find that the number of short sales actually exceeded foreclosure sales in September for the first time.
