I disagree. I think that v4-only apps and devices will get relegated to being connected through v4-v6 adapter 
appliances until they are fixed.

IPv4 is simply going to become far too expensive to maintain to be able to deliver it for residential pricing.

Of course, this doesn't mean that the ISP access needs to stay dual-stack, thanks to MAP, 464XLAT etc.


Right... Those are some of the ways that maintaining IPv4 will become so expensive. ;-)
