"During our travels through Asia last week, we con confirm that Bitmain has already developed an ASIC for mining Ethereum, and is readying the supply chain for shipments in 2Q18. The initial roll out is expected in 2Q18, but production is expected to be somewhat limited (Bitmain may use these first rigs for proprietary mining within their own infrastructure). Production volumes are expected to ramp significantly beginning in Mya, with more widespread retail availability soon after. While Bitmain is likely to be the largest ASIC vendor (currently 70% to 80% of Bitcoin mining ASICs) and the first to market with this product, we have learned of at least three other companies working on Ethereum ASICs all at various stages of development."
They dont have killer Hash rate, The real killer is how little power they use.
