An Observation of the greater Phoenix housing market

Whoa! Is this a coincidence or a new trend.  Today as I was searching through the ARMLS (Maricopa County, greater Phoenix housing) I came across two new listings in two different parts of town that were not flip, short sale or REO but good old fashioned traditional equity sales (I checked tax records).  Just yesterday we got the news we're down to 3.33 mnths of inventory in the valley based on the active listings in the MLS but now I have to ask, is this a coincidence or a trend?  I'd love to hear your thoughts and opinions on this.
