Well, that looks like that.
At midnight on the morning of 1st Feb 2011 IANA announced two more /8's allocated to APNIC (39/8 and 106/8) leaving the final five /8s, one for each of the RIRs.
The policy is that these final five /8s are allocated to the five RIRs immediately, and we expect this to be formally announced 14:30 Thursday.
So, no more allocations from IANA after that!
(Well, technically, there is a pool for returned allocations, but that is going to be a tad rare)
