Ecobee Premium and Enhanced Thermostats

Ecobee has announced two new smart thermostats…
$249.99 Ecobee Smart Thermostat Premium

What’s the over/under on whether the IAQ data from the Premium is integrated with SmartThings?

My HVAC just had an issue and fried my Ecobee 4. Perfect timing for an upgrade!
