I really, really hope that Microsoft get's over the whole "You are the Controller" thing, and includes some type of small handheld wand, with a trigger and a thumbstick on it.
Just think how that simple measure could dramatically improve immersion in Kinect games. You'd have rumble, which would provide some feedback, and you'd have the thumbstick to control your walking/running/direction. You have the trigger for any gun games. What I want, is a much better Kinect camera, with higher resolution, less input lag, better facial recognition, better voice recognition, base level head tracking, finger detection .....
AND.... a Move type controller.
The thing is, Microsoft has repeatedly stated that they don't want the consumer to have anything in their hands when they play Kinect. YOU ARE THE CONTROLLER. has been their mantra since the launch of Kinect. Still, I think it's obvious that many games would benefit tremendously if Microsoft could have a Wand type device. Baseball, Tennis, Ping-Pong, Volleyball, Shooters, Archery/Swords/Shields, etc, etc.
Probably not going to happen, but I can dream
