any confermation from bitmain on if s1 will come back, and how pricing waill be in the future?
I have a feeling their chip supply/manufacturing capacity is being converted to S2, my guess is that at this BTC price the shipping cost is starting to eat to much into their S1 profits to be worth it.
Most people think the S1 and the S2 use the same chips. My bet is the boards are almost the same as well, just undervolted.
