I found this, and surprised there isn't a lot of talk about it:
http://www.cahf.co/"CAHF chain will follow and fork existing rules of the Ethereum’s main-chain, except for issuance reduction and POS. We will maintain our POW chain which will be the Ethereum-POW chain (when Ethereum hardforks to POS)."
That means there's going to be a third Ethereum, no??
