i am more of a pessimist. i suspect that there will be enough v4-only destinations out there that multi-homed enterprises fronting onto dual-stack backbones will announce teenie bits of v4 so they can nat64.
I'll take this one a little further.
I suspect that as we reach exhaustion, more people will be forced to break space out of their provider's v4 aggregates, and announce them, and an unfiltered DFZ may well approach the 'million' entries some vendors now claim to support.
This matches my personal view (and could be viewed as "success" compared to the 5M estimate of Mr. Herrin...)

Are people going to be relying on using default-routing then in the future if they don't upgrade routers to handle large routing table growth? Or perhaps forgo dual-stack and have a separate physical IPv6 BGP network from IPv4? Are there any other strategies?
