"According to industry analysts, the reduced sales of traditional switching/routing heavyweights, during this traditionally active time, is due to widespread corporate investments and trials of software defined networking (SDN) equipment, which promises to improve routing efficiency, network management, and dramatically reduce hardware costs. Industry heavyweights like Google, Amazon, Facebook, and others are already heavily invested in OpenFlow and SDN, but it seems to be taking hold on a much wider scale, and not just in ultra-massive data centers."

I assume you're asking about the hardware [openflow.org] abstraction [openflow.org]. Think how much fancy mellanox hardware is found in datacenters.
I'm not going to address all the points in the article however I point out that TFS itself is about how sales of traditional equipment is falling due to the widespread adoption of openflow. I think this [informationweek.com] does a good job of explaining what drives adoption:
So basically, SDN is here to stay because traditional networking doesn't handle the dynamic nature of todays datacentres. You can start playing with openflow right now because it's integrated into openqrm and probably all of the other provisioning magic sauce too.
Also, I said above "We're talking about potentially not even using ethernet and TCP/IP." I want to clarify that I said that to try and explain what SDN is. While ethernet and to some extent IP are on the chopping block, the Linux TCP stack is going to be with us for a very long time.

I'm not familiar with mellanox hardware, i'll have to check it out. I was asking more for an actual example, but the links you provided will do. I have no doubt that SDN is here to stay,my problem lies with the way it is being pushed down our throats as the next big thing while the exact "nuts and bolts" of it remain a mystery for the vast majority of network professionals. Same thing happened with the "cloud" - last time i visited the openstack homepage it was a shitstorm of buzzwords and you'd have to dig for hours in order to find some technical document. As the article i posted says:
