Xbox One does not have a required internet comnection. Its actually the sane as the 360. You can play SP games offline but not MP. You cannot use TV, Marketplace, or anything like that. Kinect funcionality will still continue to work.

Also there hasn't been much talk about the Steambok in a while...

There may be a couple of things on this chart that are wrong, after all I just pulled it from IGN!
