Intel has enormous 14nm capacity and the node has been fully depreciated for years now, I wouldn't be surprised to see them keep it around long past its time in the zeitgeist. I'd be willing to bet we're about a generation away from a deluge of demand for embedded chips made on that node. Several high-end microcontrollers are made on 18nm processes already.

I'm still rooting for them to separate the fabs from the IP, I just wouldn't be surprised if some of the fabs stick around longer than folks would expect.
