New SmartThings App and Ecosystem

Any information on konnected smartapps being updated for use in the new SmartThings ecosystem? As it stand right now, all custom or third party device type handlers are not functioning within the new ecosystem.

SmartThings still has not set a sunset date for the current Groovy-based SmartApp/DeviceType setup. I don't see them doing that anytime soon as it would lead to a full scale revolt within the developer community.
