Eventually you reach the limits of thermodynamics then you buy because they won't be anything faster coming out later.
22 nm 2012
14 nm 2013
10 nm est. 2015
7 nm est. 2017
5 nm est. 2019
Not sure how many bitcoins will be left by 2019 though? 21m - 17m (2019 est.) = 4m?
Have you forgotten the halvings or is this just me.. 22 nm 2012
14 nm 2013
10 nm est. 2015

5 nm est. 2019

Have you forgotten how technology works or is it just me.
Intel and the big computer companies are just barely beginning to scratch 20 nm in marketable products, their R&D are working on 14 nm. If billion dollar companies/industries take this long to drop nm's, what makes you think bitcoin mining hardware is just going to sail through them?
We'll be at 28 nm for 5 years at least.
Well the problem is, that process shrinking does no more shrink the relative transistor costs in the amount we have seen a few years ago. If its no more possible to shrink the relative costs of a transistor this would mean the end of moors law. Thats why the whole industry is in panic: See this famous NVIDIA flame for ex: http://www.extremetech.com/computing/123529-nvidia-deeply-unhappy-with-tsmc-claims-22nm-essentially-worthless
However this freeze are basically good news for miners. Since it would mean a halt in cost saving advancements, and makes they're mining gear longer profitable operational. The only problem is, that the current products are highly overpriced and there is a huge cost saving potential.
