IBM has already announced they're researching 8nm (IIRC) for the next generation process.
So here is what is confusing. If 14/16nm is due out within a few months, this would severely shorten the useful life of the A6/S7 models. Yet the network hash seems to say that a lot of money was dumped on these very models. If true, even the big boys might have problems with ROI. One wonders if BITMAIN et al would recoup their 1385 development costs. You would think the the competitive intel of the bigs would be accurate.
Speaking of IBM, one of their old tricks used to be to pre announce their next model of large systems to forestall customers from buying their competitors hardware.
of course Bitmain will recoup their costs
their miners are selling as fast as they can make them
their customers might not be as lucky though
not sure about Avalon they aren't interested in selling in small quantities and their pricing sucks
