Reports coming out that a Wii U day-one firmware update is bricking units if power is lost during the update. Other users are reporting that the 5GB download bricks the system if Internet connectivity is lost. Out of the box, the Wii U isn’t useful for much more than playing games. The launch-day update is needed to activate system features ranging from the new Miiverse social network and online eShop to the ability to play older Wii games on the system. Nintendo has yet to issue an official comment on the bricked consoles.
WIkipedia describes the console:
The Wii U is a video game console from Nintendo and the successor to the Wii. It was released on November 18, 2012 in North America, and is scheduled for release on November 30, 2012 in Europe and Australia, and December 8, 2012 in Japan. It is the first entry in the eighth generation of video game home consoles.
The Wii U is the first Nintendo console to support high-definition graphics, capable of producing video output up to 1080p. It has 2 GB of memory with half dedicated to the console’s operating system. The console was released in two versions: a “Basic” white-colored version with 8 GB of internal Flash storage; and a “Deluxe” black-colored version with 32 GB of Flash storage, which includes stand and docks. The Wii U’s primary controller is the Wii U GamePad, which features an embedded touchscreen. The touchscreen is used to supplement the main gameplay shown on the television or, with supported games, can allow the player to continue playing games by displaying the main gameplay even when the television is off. In addition to the Wii U GamePad, a more traditional controller, called the Wii U Pro Controller, may be used.
The system is backward compatible with Wii, and Wii U games may support compatibility with Wii peripherals, such as the Wii Remote Plus and the Nunchuk. While it is not backward compatible with Nintendo GameCube discs or peripherals, GameCube titles will become available for purchase and download from Nintendo’s Virtual Console service.
