When will Apple Music be fully integrated with SONOS?

SONOS & Spotify made this work a long time ago, and I dared hope Apple Music would have followed suit pretty quickly. An age has passed and still nothing.

Is there any kind of time frame as to when this might happen? Having no correlation between the SONOS app and the Apple Music App on iOS or iTunes on the Mac is a pain...surely full integration can't be that difficult to achieve, can it?

Please at least give us some idea of when we can expect this.
