I have not heard all the details about this new console yet, but there were a couple of things that struck me about the controller.
It certainly looks different than your average games controller. It comes with a built in 6.2" screen so you can carry on playing the game even when somebody else want to use the TV. It is a touch screen so you can use a stylus or no doubt your finger. Other features of the controller is it has a built in microphone, a front facing camera and a gyroscope as well as your normal analog controllers to acccompany the D-Pad and buttons.
It will also be backward compatible with items such as the Wii Balance board, so for example if you are a little shy about weighing yourself on the board, you can have the output only display on the screen on the controller.
As always I am always interested in your thoughts so if you have any comments or feedback then please feel free to add any comments, or you can mail me here.
