Never's a long time.  I think you might be right, but only because I
expect Internet governance to implode before 6 overtakes 4 as the
default IP version.  If not for that, I would expect IPv6 to reach a
point where IPv4 is but a quaint curiosity within times I can
reasonably expect to live to see - say, the next 30 years.

When I worked in Tromsø for the second half of 2002, the house netlink
they set me up with was globally routable - but v6-only.  And that was
over seven years ago.  Adoption is going to be slower in the
world-facing-MTA space, but not so much slower that, well, see above.
