well i have to admit that i dont see the use of pushing out even more hash against many more watts, noise, heat, and shorter lifespan.
What i'm interested in, is the asicboost option,like dragonmint T1.
I can imagine that it might be a bunny out  of the hat of bitmain, in order to re-sell their "new S9Tix"with asicboost support, to generate an attractive new model, and have a new income based on hardware they already developed and produce in large quantity. (in other wordt: why release it just right now as you already are as good as unbeatable...? You'd give away your pearls on forehand and have nothing in the magic hat anymore to compete...)

I think its a viableoption that has been "discovered" by an other team right now...

So, yeah. If they do well and it works: why not. (supposing your pool can handle it.)
