You're mixing problems.
Even though you may only be able to put in a new route processor
every 3-5 years doesn't mean the vendor shouldn't have a faster version every 18 months, or even sooner. It's the addition of the two that's the problem. You're 5 year cycle may come a year before
the vendors 5 year cycle, putting you on 9 year old gear before you refresh next.
The vendor has to qualify, write code for, and support n versions. This IS a part of the problem. Just blindly swapping out CPUs is non trivial, as any systems engineer can tell you. The support cost will be passed on to the consumer.

Vendor J got it half right. The RP is a separately replaceable
component based on a commodity motherboard, hooked in with commodity ethernet, using the most popular CPU and ram on the market. And yes, I understand needing to pay extra for the sheet metal, cooling calculations, and other items.
But, they still cost 10x a PC based on the same components, and are upgraded perhaps every 3 years, at best. They don't even take advantage of perhaps going from a 2.0Ghz processor to a 2.4, using the same motherboard, RAM, disk, etc.
But I think the point still stands, I bet Vendor J in particular could pop out a Core 2 Duo based RP with 8 gig of ram and a 300+ gig hard drive in under 6 months while holding the price point if BGP convergence demanded it, and their customers made it a priority.
To Bill's original e-mail. Can we count on 2x every 18 months going forward? No. But betting on 2x every 24 months, and accounting for the delta between currently shipping and currently available hardware seems
completely reasonable when assessing the real problem.
