Well this is interesting. The AirPlay webpage on Apple’s website has been updated to reference smart TV’s by other manufacturers are getting AirPlay 2.
Leading TV manufacturers are integrating AirPlay 2 directly into their TVs, so now you can effortlessly share or mirror almost anything from your iOS device or Mac directly to your AirPlay 2–enabled smart TV.
There’s an on-off rumour circulating that Apple is considering a launch of its own video service, so having AirPlay 2 inside as many home theatre and smart screens as possible makes perfect sense. They’d want to be everywhere, fast. There’s going to be a load of people out there without Apple TV’s but who own at least one iOS device.
