Some info:
It is a combination of a more traditional interface—as previously reported, the New Controller has two analog sticks, one d-pad, four face buttons, two shoulder buttons and two triggers—and the tilting, turning and shaking motion controls that made the Wii a smash success.
The new controller also incorporates a large touchscreen interface, a front-facing camera, gyroscope, and microphone.
Nintendo offered the following loose technical specifications to Kotaku in a pre-briefing on Nintendo's New Console.
* High definition display, up to 1080p resolution via HDMI output

* Internal flash-based media storage, upgradeable via USB and SD carts
* Games ship on proprietary iDensity discs of unspecified, but "large capacity"
* Games will also be available as downloadable content
* Console compatible with Wii games and devices
* Release date between April 1, 2012 to December 31, 2012; or after the end of Nintendo's fiscal year
