As I recall Franks last predictions came in at 2008 +/- 5 years.  One thing
to note about those predictions is that Frank worked off of Internic
allocations and didn't have APNIC or RIPE data (if I am wrong please
correct me Frank, but this point does stick in my mind), so from the data
he used he didn't know that RIPE and APNIC were close to filling their
previously assigned blocks and would need large delegations of /8's.  These
large type of allocations put large spikes in the curves and certainly
hasten the exhaustion problem.
