The Xbox One will remember what you were last doing, with the entire console controllable by your voice. Saying 'watch TV' to your Xbox, bumps up live TV to your eyes. Not only that, you can use "Instant Switching", where you say "Xbox Game" and then "Go To TV" and then "Go To Music", followed by "Watch TV" and there are literally seconds between each new command. Impressive.
New gestures are at play thanks to next-gen consoles, with some impressive gestures at play.
