Again its not clear to me what you mean by 'predictable." Yes, in
effect a market for a good prices itself against the cost of
alternatives, and a market in IPv4 may well perceivce NATs and IPv6
as alternatives and prices within such an IPv4 market may well
reflect the perceived cost (and benefit) of such alternatives. My
question to you is whether this is what you mean by a predictable
outcome, or are you hinting at some other view of the behaviour of
such a market?

There is the view that its not the date of exhaustion that is the
issue for industry - its the transition from the address distribution
system we use today to what happens thereafter that is critical to
industry stability here. The entire issue of demand levels of
continued deployment of IPv4 and the likely levels of industry
attention to alternatives look to be critical factors here when
thinking about such transitions. Its an topic that appears to call
for a broader (multi-disciplinary?) approach to understand the full
extent of the industry dynamics here, and it certainly appears to be
more than just the perspective of looking at this as a choice set of
technically feasible alternatives being presented to a relatively
homogenous industry that is capable of making coordinated decisions.
