Kinect support for Skyrim will be available, free for everyone, tomorrow. The RPG will soon support more than 200 voice commands to help you through the game's many menues. You'll also be able to finally yell at your TV, and have it respond! I've been yelling at my TV for years, before it was cool, so I'm kind of a hipster like that.
Dragon Shouts can be applied to Skyrim by either actually saying the shout (IE: "Fus Ro DAH!") or simply stating the name of the shout (IE: "Unrelenting Force!") You'll also be able to easily command followers, assign hotkeys, change weapons and otherwise alter your game with your voice.
Along with the voice commands will come the ability to sort inventory by weight or value, which I think we all desperately need, and the ability to set loot value limits, so no more manually picking out useful items from among a hoard of garbage.
