Theory: The reason bitmain put out that announcement saying that they’ll dedicate their hash power to their own big block bitcoin chain is because the moment segwit becomes active their hash rate will drop by ~15% due to ASIC boost being disabled, and that’d be obvious, so they need a cover up
That's also why they'll be starting it exactly 12 hours after segwit starts. Because then they'll be able to say that their hash rate dropped because they were setting things up for China Coin.
