Has any information been posted about AirPlay 2? I'm just wondering why it needs to exist. Apple says that it allows you to play the same music on multiple speakers around a house, but AirPlay has supported that feature for years; I play music from iTunes on my Mac on the Mac itself, an AirPlay speaker in the bedroom and an Apple TV in the living room and they are perfectly synchronized. So what does AirPlay 2 bring to the table? How will AirPlay 1 devices be supported? I figured we could use a thread for gathering this information as it comes available.
