Satoru Iwata announced during the Nintendo Direct pre-E3 stream that the Wii U controller/tablet will officially be called Wii U GamePad, a nod to the NES gamepad, and it will be slightly different than the prototype unveiled at least year’s E3.
More details after the break.
The Wii U GamePad still has the same expected features such as touchscreen capabilities using either your fingers or a stylus, detects motion sensor and gyro sensors, and can be linked with the Wiimote, Wii Nunchuck Controller and the Balance Board. Players will also be able to use a traditional controller if preferred called the Wii U Pro Controller.
The internet can be browsed on Wii U, which can be displayed both on the GamePad and on the TV screen. Players will also have the option to display content from the GamePad onto the TV or not with the Curtain feature. With the Curtain closed, an actual curtain will be displayed on the TV, and with it open, content from the GamePad will be displayed on the TV.
As far as changes go: Buttons were moved and grips were changed to make the GamePad feel more comfortable. The sliders are now thumbsticks which can be pushed down.
