In my research about SDN I have read recently a very interesting blog post about technologies in IT. The post has a strong emphasis on merging of new technologies and its later on evolution on the market. I higly recomed to take a look at the full blog that can be found here: SDN, Career choices and magic graphs

That said unfortunately I still didn't find the answer for my question about a future of SDN in networking but I'm definitely one step closer to it.
