When do you think that will happen and in what percentages of your 
target populations to matter?

There is a phase you are missing between depletion and v6 only hosts.

That would be continual and increasing difficulties of obtaining new v4 
access and degradation of the quality of that service, hopefully along 
with a direct inverse effect on the quality and resultant value of v6 
service.

The time line and gradations of that phase are far less clear than 
depletion.

That would explain why so many do not concern themselves with it at this 
time. Especially those who do not consider themselves to be the party 
initially responsible for resolving those issues.
