I think the disconnect is that the vendors are claiming massive numbers, but 
it'll be N years before those routers are deployed at every single point 
they're required, and N is expected to be large enough to render the 
vendors' claims irrelevant for current discussions.  Even those that replace 
their "core" routers every ~3 years just push them down to the next level in 
the network; even if those 10M-route beasts will be available in 2 years, N 
will is going to be large enough we can't use them as the basis for policies 
we're making today.

Vendors always base their pitches on the crazy idea that every customers 
will replace every router in their network every couple of years just 
because they have some cool new chassis or linecard available, which I'm 
sure would be very lucrative for them but isn't realistic.  In the words of 
Bandy Rush, I encourage my competitors to do that...
