That makes sense in a 'market' kind of way, however I expect v6 adoption to
be much less of a cost curve and more of a flood gate as vendors start
rolling out better support, or any support for v6.

It's difficult for me to imagine any kind of v4 address market extending
the life of the public v4-only internet more than a few months, any more
than 2 or 3 legacy /8s getting returned to the global pool would. There's
just too much growth and too few networks that would get those addresses to
be significant in the larger picture.

I do agree that v4 will continue to survive for quite some time though, but
not at the expense of v6 adoption.
