Apple has its users hypnotized into buying new hardware they don't need. There is nothing the Apple tv needs as a media device that can't be added through software updates.
It's like you are begging apple to release a new device just to buy it because you are bored and have money to burn.
The only thing Apple tv needs is something most of you don't use or know nothing about and can also be added through software.
It needs pass-through audio for hi end home theaters to not use the internal dac in the box and to also allow hi res audio with Apple music to be passed to standalone dac.
THATS IT! THERE IS NOTHING ELSE NEEDED.
