That somewhat mirrors my take on it.  At the risk of being flamed to hell, 
I see SDN/NFV being to network operations as DevOps/CI/CM/containers are to 
dev and systems.  Both are bringing in new tools and such, but ultimately 
they *require* solid automation and having your house (systems, processes 
workflow) in order to be able to deploy, with the hype train providing 
budget allocation and sufficient buy-in to get it to fly.

You can do network automation and service provisioning without NFV and 
centralized SDN controllers, and you can do CM and good tooling without 
going headlong into DevOps.  Obviously SDN/NFV and DevOps have their own 
pieces that layer on top of that (e.g.  control plane / forwarding plane 
separation and commoditization of the forwarding hardware in the former; 
development model and "culture" in the latter), and you have to sift 
through the hype and buzzword bingo to find what if any of that would 
deliver value in your environment.  But, that doesn't mean we can't benefit 
from the advances and possible standardization in tooling and automation 
that come along for the ride.
