ETH Berlin Hardfork – New Coin?

I'm curious if miners will fork it and essentially create an "EthereumCash" type of chain thats forked off of it, to continue mining it and profiting/dumping it. This seems that it would be a win/win for everyone, miners and ETH holders.

ETH holders get something to sell and dump to buy more ETH. – Miners get something they can milk until its no longer profitable.

Only losers would be people actually buying it.

What are the chances of this happening?

I believe the similar thing happened in the 2017 top with Bitcoin and BCH.
