At the moment of RIR IPv4 depletion, there'll will be variation
among individual ISPs in the amount of IPv4 space remaining
for new customer growth (based on the time and size of their
last allocation per NRPM 4.2.2 or 4.2.4).  Given the limited
customer benefits of IPv6, customers are likely to value the
status quo and seek ISPs who still have available IPv4 space
just as you noted above.   However, one would expect these
ISPs to deplete their last allocation at an accelerated pace
and (in the absence of some alternative solution) wouldn't
this make ISP shopping for IPv4 simply a transient condition?
