im sure they release a new asic one day after the coupons expire.
probably EtHash...
Have you not done research into ETH's discussion on fork to PROG Proof of Work? They already said they will fork. So, why should Bitmain make an attempt at another ASIC for ETH if a fork is coming?
because they are already using them,
now its time to sell them..
just a guess..
maybe there is no real ethash asic..
i dont know-
