Exactly.

Assuming the IETF can even cause ISPs to hand out /48s, which it cannot, the other side of that coin is that now the address space increase becomes rather ho-hum. An extra 16 bits, effectively, is only an increase of 4 1/2 orders of magnitude. Which, considering how far we have already gotten beyond un-NATed IPv4, and considering the number of addition gizmos are to connect to the Internet in the not so distant future, is just nothing to write home about.
