During the Electronic Entertainment Expo (E3) in Los Angeles, Nintendo finally revealed the details of its long-awaited the next generation Wii console, the Wii U, featured by a 6.2 inch touch-screen controller.

Wii U is Nintendo's first console that supports HD graphics, providing its gamers not only with high-quality and powerful graphics on the TV, but also with the full gaming experience on the Wii U's mobile screen by featuring an accelerometer, a gyroscope, a rumble feature, a microphone, speakers and an inward-facing camera.

Users can play games with touch-screen control, but it still has classic control scheme such as two analog Circle Pads, + Control Pad, A/B/X/Y buttons, L/R buttons, and ZL/ZR buttons. These features are aimed to attract “core users.”

According to the announcement by Nintendo, the release of Wii U will be between April and December 2012. They didn't mention the price, but it is presumed around $300.

Wii, the previous model of Wii U, is one of the highest sold home video game consoles. To date, more than 86 million units of Wii have been sold. But after 5 years of its launch, its sales have vastly decreased.

This February, Nintendo released a new portable console, Nintendo 3DS to fill the gap left by Wii. But it failed to meet the sales expectations. Hence, Nintendo is now banking on Wii U's success.
