Random thought I have recently: Seeing how ProMotion allowed content to be 120 fps instead of just 60 fps, to allow people to mirror these content to screens that support such frame rates, Apple may be working on improving AirPlay to make it efficient enough to push the higher amount of data needed. This will mean AirPlay will be improved in future iOSes (as soon as 11?) and also any AirPlay related hardware (e.g. Apple TV and Lightning Digital AV adapter) will receive such improvement whether via updates for software/firmware respectively, or even hardware refreshes to accommodate this. What do you all think?
