How about Stellite, Turtle, Bitcoal , Dero, Edollar and a dozen other tradable CN coins? Most of them just started and are more profitable to mine. Each week there's a new one coming out, keeping the original cryptonight algorithm. I hope it's gonna be like you say, otherwise all small miners with will get smashed like bugs.
Other coins have <60Mh combined.
TRTL, EDL, DERO probably fork too (

Bitcoal has only ~0.3Mh.
I think most cryptonight coins with active developers will follow XMR (if fork succeed).
