This is a sad month for all bitcoin users. We are now faced with the possibility of a split community the other one is with the core developers while the other group is with Bitcoin Unlimited. It is sad to see that bitcoin will split into BTC and BTU however it seems that this time we can no longer meet a consensus and thus bitcoin will split like Ethereum and Ethereum Classic.
I don't think it will split. BU only serves to not activate Segwit. Miners don't want BU either.
