According to Digitimes, TSMC has received an urgent order from Bitmain for 100k 12nm HPC (high performance computing) chips at the beginning of 2018. 10k chips will be delivered every month in Q1 2018 and more in Q2.
So what are this chips going to become? If they are getting these chips in Q1, product sales will start soon. Or maybe they are producing next-gen hardware for them and we won't see the new miners for months?
