I don't see that happening either.  What most people seem to be predicting 
is that, at some point, IPv4 service will cost more than IPv6 service and 
the gap will widen as the people who can jump off the IPv4 ship do so and 
there's fewer and fewer people to spread the costs of dual-stacking across.

That's what NAT is for.  The IETF wants nothing to do with that transition 
model, but the market will want it anyways and so the vendors will ship it. 
You can't pay your shareholders with dogma.
