Respectfully, I disagree. If the major content providers were to deploy
IPv6 within the next 6 months (pretty achievable even now), then the
need for CGN would at least be very much reduced, if not virtually
eliminated.

Surely the case is that you've still got the same number of users who need an
IPv4 address to be able to access "legacy" IPv4 sites on the Internet - until
100% of content is accessible via IPv6.

What it does, however, change is the amount of traffic which would need to 
flow through a CGN box.

Unfortunately, CGN is here until either everything is available over IPv6, or
a better version of NAT64 which doesn't depend on DNS rewriting is designed
and deployed.
