This is excellent news!

My main comment is that we want to avoid designing a routing scheme that
implies there's only one sink/source at a time. I can see a number of
applications (car, set-top box, multimedia PC) where you would want to have
two 'zones', eg play the movie soundtrack or game sounds+alerts on hdmi
while using Bluetooth HSP for VoIP calls.
