I think he's saying that everyone should be using dual-stack, because
that's so much easier to roll out and maintain, and there's still plenty
of IPv4 left in the US region.

(Let me say that if *I* had a mobile network where I pretty much know 
what sort of devices and stacks are being used, I'd go for IPv6-only PDP
plus 464xlat as well.  On "DSL style" end user connections, with a 
gazillion of unknown devices and applications, I'd more likely go for
IPv6+DS-Lite or IPv6+MAP - or full dual-stack *if* I had the addresses,
which is one of the small obstacles Doug seems to conveniently overlook...)
