There are already builders out of China that you can approach for custom solutions. I also wouldn't expect Marvell or Intel(especially with their acquisition of Fulcrum Microsystems last year) to sit by idly.
Another interesting thing we'll start to see is the use of concurrent programming languages by the established vendors to stay heavily involved and dare I say relevant?

It is not hard to guess this is for their SDN and OpenFlow plans.
