Here are some interesting data points for this group to consider.  
According to the U.N., world economic growth dropped from 3.5-4% in 
2003-2007 to 2.5% in 2008, and the prediction is for around 1% growth in 
2009.  At the same time, Geoff Huston's numbers have been shifting to 
the right.  In the case of IANA the number has shifted out 6 months in 6 
months.  We have not seen quite the same shift for RIR numbers, 
however.  Is world economic growth a controlling variable in the 
equation of IP address consumption, or merely a coincidence, and how can 
we tell?
