A prototype version of Wii U was showcased at E3 2011. The design of the console and controller were not definitive versions.[48] The controller demonstrated a touch screen over 6 inches wide and contained a built-in microphone, speakers, gyroscope, accelerometer, rumble and camera. All processing is done on the console itself, the output of which can be displayed either on a TV, the controller, or both simultaneously; however, the screen only supports single touch, not multitouch, going against a popular trend across the technology industry, and, at the time of unveiling, the system only supported output to one tablet controller at a time, though Nintendo is reportedly looking into allowing for such functionality in the final version of the hardware.[50] Games that were confirmed are LEGO City Stories, a new Super Smash Bros. game, and the movement from Wii to Wii U of the long-in-development Pikmin 3. A list of third party titles was also announced to be available at release.
The Wii U GamePad is the main controller for the Wii U. It features a built-in touchscreen, which can either supplement or replicate the gameplay shown on the main display, even functioning as a standalone screen without the use of a television. The controller also features an accelerometer, gyroscope, camera, dual analog sticks, as well as a built-in microphone, and support for Near field communications. (which can be used for, among other uses, figurines that can interact with the console, wireless credit card payments with compatible cards).The console will also be compatible with the Wii Remote, Wii Nunchuk and Wii Balance Board, as well as a Wii U Pro Controller for more traditional controls. Two Game Pads are supported per console.
Shigeru Miyamoto promoted the idea of the Game Pad because he supports being able to use a secondary screen while someone else is watching the television. Wii U is said to offer asymmetric competition, where the player using the Game Pad has one experience and wins in a certain way, while competing players have different ways to play and win.
CPU
The Wii U CPU is designed by IBM. It is described by IBM as an "all-new, Power-based microprocessor",the processor is a multi-core design manufactured at 45 nm with an eDRAM cache. Although neither Nintendo nor IBM has revealed detailed specifications, such as the number of cores, clock rate, or cache sizes, references to the chip containing "a lot" of eDRAM and "the same processor technology found in Watson" indicate that the processor shares some characteristics with IBM's POWER7 processor, which powers the Watson computer system and incorporates a large L3 eDRAM cache.
The Wii U CPU will be produced by IBM at their 300 mm semiconductor manufacturing facility in East Fishkill, New York.
System software
The Miiverse is the main screen for Wii U. It is a tile-based interface that features Miis of the console owner and people around the world; it shows both the console owner's tastes and global trends.
Eventually, the Miiverse will be accessible from any Web-enabled mobile device.
