Re: Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order
Here is a chart that you can use that will help.
I have updated it with Bitmains latest offering of the Antminer S9.
It seems that the network difficulty will be dropping. Perhaps due to BCH taking a little of the mining hardware out of the picture or older hardware being taken offline to to operating costs.

Amazing research man, great job! Can't wait to see the new calculations with the yet-to-be-released chips.
Anyway, if I am reading this right, ROI of 1 S9 will be 1 year (if the current BTC price remains unchanged) by November 2018.
It is more than highly unlikely to have the same BTC price by Nov, so I think that all S9 owners are pretty safe, right?
