It does depend largely on the price of BTC. I've had my first S9 over a year now and there have been times when it was earning very little (in GBP) but the profitability returned when the price rose (as did the value of the previously mined BTC, which I held, making those less profitable times more profitable). I think if the predictions of a BTC price of over $20K by June/July (and $50K by the end of the year) turn out to be correct, the S9 should remain profitable for some time yet. I think the greater threat to the S9 is a new and more efficient/powerful miner but, with so many S9s out there already (perhaps hundreds of thousands?), it would take a while for a new miner to become widespread enough to significantly affect the mining difficulty.
