Wii U
The Wii U is the upcomming home console by Nintendo, and the successor to the Wii. The Wii U is Nintendo's sixth home console and will be capable of displaying high-resolution graphics similar to the Xbox 360 and the PS3.
The Wii U will come with a new type of controller, the Wii U gamepad. This new controller's main two features are the embedded touchscreen and its ability to use the touchscreen for displaying games, even after the television screen has turned off.
The Wii U, aside from its unique controller, will also have a secondary controller (sold separately) called the Wii U Pro. This controller features the same button layout as the gamepad, but on a more compact design with no touchscreen, for use by the more "core gamers".
Due to the Wii U's processing power and overall preformance, the Wii U will hold the place of the world's most powerful console once it launches, with capabilities surpassing that of the Xbox360 and PS3.
Backwards Compatibility
The Wii U will be backwards compatible with all Wii games. It will not be, however, capable of playing Gamecube games or peripherals.
However, many games from Gamecube and other consoles before that will be available for purchase as virtual console titles.
