I think part of reason of making this thread is to worry other makers. They were smart to keep same nm and master it. I think they will be able to make a lot by doing this.
I still wonder on time frame though. Once they get producing them I predict a lot coming fast of the new product.
Well I think with the smaller nm chips there's a huge problem of power consumption.. Intel is dealing with this now on their new gen stuff in the works.. So Bitmain is the winner here even with LKETC and their 14nm.. The power draw from their new chip will be comparable to bitmains fully custom 28nm
