There are two possible results, it seems to me:

1. The cost of deploying IPv6 will "bury" the cost of doing BGPsec, so
that BGPsec essentially becomes "free" in the IPv6 upgrade.

WEG] Two or three years ago I might have at least partially agreed with the above. Now, most large-scale ISPs have IPv6 deployed, using hardware that they have been assured (through testing and contracts) can forward IPv6 traffic at linerate. I believe that there are plenty of places where there is real traffic running such that the concept that somehow we're all cruising towards disaster if this IPv6 thing ever gets real is FUD at best anymore. There is also a big difference in my mind between forwarding hardware and routing hardware, so talking about v6 forwarding is conflating the two in an unhelpful way.
However, rather than an assumption that the two share a timeline, I think that this implies that IPv6 deployments may have the net effect of knocking some of the oldest crap out of the network, which makes more sense to me. Even then, all it'll do is bring things up to today's state of the art (+/- 2 years), so I think Randy's assumption about today's state of the art being the absolute best that you can assume when modeling for 3-5+ years from now is a good one.
