The Nintendo 3DS was officially announced at this Summer's E3 conference, and now we know more details about the highly anticipated device. The 3DS comes with a charger stand, a 3DS touch pen, a 2GB SD card, and six augmented reality cards. New functions include a slide pad, motion sensor, and gyro sensor.

Like its DS family predecessors, the 3DS features two screens. The top, 3.53 inches with a liquid crystal display of 800 x 240 pixels. The button, 3.02 inches with a liquid crystal display of 320 x 240 pixels. Games can be downloaded from the 3DS Virtual Console and will also work with DS and DSi game cartridges. It comes in three colors: blue, red, and gray.

The 3DS launches in Japan — with streaming 3D TV! — in February for $298 and will launch in the US a month later. So far, no word on streaming TV or a US price.
