IPv4 addresses are not "out". There are a finite number of IPv4 addresses just as there is a finite amount of land on earth. We are not "out" of land are we? The regional registries haven't even finished allocating the addresses (let alone the low utilization rate of allocated addresses).

If the need of migrating to IPv6 is so great and it so valuable to do so, why the need for artificial pronouncements?

Yes, IPv6 is about 13-years old (from draft RFC approval in 1998). I view this as a more of a failure of IPv6, however.

Again, I meant that IPv4's time is out. I have edited my comment to clarify this.
