Apple announced AirPlay 2 at WWDC today. It will offer multi-room audio from iOS. It appears that it will be part of HomeKit, so it should be configurable. Not sure if it will be backward compatible with all AirPlay devices at this point, but they did say it works with the newer Appletv, so it will at least work with some products already on the market. The Homepod is the $350 Echo/Home competitor. It sounds like they have some room acoustics built in. It is priced a lot higher than I was expecting, but I think they are trying to compete with Sonos rather than the Echo. They also mentioned that Apple Music had 27 million subscribers now, so it is still growing. I am sure we will get a lot more info closer to the release dates.
