Or PVR or cable box, which so many people have already. That's what HDMI throughput and CEC handshaking was supposed to be for, I thought. Maybe this device is aimed at a niche like bedroom/dorm room?
It's being targeted at those that don't have any box in Europe. Those people wouldn't be able to use the Live TV functions on the Xbox One at all. From all the comments I've read on Reddit & the Xbox Feedback site supposedly Europe has a larger group people than the US that gets their TV channels this way. So an HDMI In would basically go unused in those markets.
