yep. its gonna be ugly once ETH mining stops.
ETCseems to be holding price for now and they have diffused the difficulty bomb so probably will keep the same. So yeah, Zclassic, ZEC, ETC, XMR, lbry, Silk are going to be coins left for mining
Profitability will likely be half to less than half of what we see now. That means any gfxcard that uses high power/hash ratio will take a hit. Anyone who has got higher cost of electricity will take a hit first. So basically all the miners are in for a bad time.

When the ETH stops PoW, it will be a dead coin like the XRP or NXT. It will not have support from the miners.
