I have a few questions about the xbone that have been bugging me. If anyone knows answers to any of these questions, that would be awesome.

1. If the xbox can control your cable box through the hdmi connection, can it also control your tv? I would love to put the remote away for good. Simply walk in the room and have a voice command to turn everything on.

2. Does the xbone have an optical audio output?

3. Skype calls are in 1080p, but at what refresh rate? If its 60fps over a good connection I will be blown away, I couldn't find a single 1080p webcam that can do that.

4. Is it better to purchase physical disks or download them digitally? (This is more asking your preference)
