This thing is going to fucking tank, I'm calling it now.
No gamer cares about this stuff, and no regular person is going to see a reason why they need a magic hand waving camera because, despite what MS is claiming, pressing the "input" button on my remote isn't very difficult. In fact, I have a very expensive home receiver with two output zones, a good 8 HDMI ins, two HDMI outs, audio ins, SPDIF connectors, etc. I use all this stuff because i hook several instruments, MFX petals, DJ controllers, etc; up to my living room sound system.
Quite frankly, I'm someone who is very frequently switching inputs and outputs, but it's really not that hard. Nor do I think the xbox one is going to have anywhere near the amount of inputs I need.
