So...respectfully...I can totally see a use for a camera here despite other commenters proclaiming how "absurd" it is. Personally I'd have no problem perching my ATV on top of my entertainment cabinet, with a clear line of site to the couch so the camera could see me. The wife and I have kids in other cities, and it would be great to be able to Facetime with them on the big screen without the awkwardness of the other person seeing what's coming through the phone camera in my hand. and, as for using a phone or iPad as a camera instead, well, I've tried that multiple times with my Mac Mini and the experience SUCKS. The camera never stays connected, sometimes it works only when plugged in, it needs to be on a charging cable...it's just not a very smooth experience. I would think a fixed, dedicated camera on the ATW would work quite well here, and it would likely to provide the "center stage" feature that iPads have where the camera moves to the person on the couch doing the speaking.
Additionally I would hope that the new model, if in fact it comes with a camera, also includes a USB-C port for a 3rd party camera for those of you with the ATV tucked away in a cabinet.
