By the time its launched, zec will be less profitable then eth... I got all my machines switched over to zcash finally running stable and the price has dropped by 50% while difficulty increases 200% every couple days. another week i might switch back to eth for stability.
Yeah I'm watching ETH and XMR to try to decide when to resume mining them. It's really hard to predict when that point will be - when everyone else switches back over is too late

The rule that hashrate follows price is obviously kind of broken in XMR. I guess due to the many botnets which mine for free. The same could happen to ZEC soon. CPU coins suck.
