B&O is actually ready to push the sw update to enable AirPlay 2.0, but they will have to wait for Apple to launch and distribute it for their own products first. B&O says that Apple will do so during the first months of 2018... not very accurate, but I guess this is Apple's way of doing things😁
A more interesting note, at least to me, is that some of their wireless speakers will get built-in voice control later in 2018. They have a prototype BS1 at CES.
