Two important things:
1) In China there is currently a crackdown going on against anything BTC. It may mean that the december batch (from Bitmain, located in China) will never arrive.
2) What has not been addressed so far: Gigawatt does not turn off your miner even when mining profits are lower than MEF (electricity/hosting). Gigawatt does not turn off or destroy your miner, it offers only to ship it to you once it's not profitable anymore. You pay for the costs of shipping/customs which will be a lot if you order several miners.
For China, bitcoin mining generates millions of dollars a day in bitcoin that can be sold offshore - i.e., it's a potential source of foreign exchange income. What's more, the more bitcoin rises in price, the higher the dollar-equivalent value of those mining rewards (i.e. currently 12.5 bitcoin every 10 minutes approximately).
And take a look at statement from the exchange ViaBTC, it announced that Its mining pool is unaffected.
Putting this all together suggests to me that mining will continue unaffected, and mining chip producer s like bitmain will continue working.
