No one is even close to shipping production sub-14nm chips. See edit. a big Hmm here...
Engineering samples of test circuits to begin characterizing what to expect from them -- maybe. After the almost-there for a couple years hopes the 16/14nm showed (and even though in now production are still producing horrible yields) most industry pundits still put any 10nm production from even Intel/IBM to be early next year. Even then they still follow that with - maybe.

Edit: Just did a search on Samsung and turned up https://arstechnica.com/gadgets/2017/02/samsungs-got-a-new-10nm-octa-core-chip-with-gigabit-lte-for-flagship-phones/
And from March, http://www.eetimes.com/document.asp?doc_id=1331504

wtf? There has been NO mention about that kind of progress in the IEEE Spectrum feeds I get. Those cover beyond-bleeding-edge tech and last I read 10nm was still in test-mode so this bears looking into...
