During its Nintendo Media Summit press conference in Japan, Nintendo’s CEO Satoru Iwata has revealed the Nintendo DSi, the latest Nintendo handheld with an even slicker design and more features than the extremely popular Nintendo DS Lite.

The Nintendo DSi is 12% or 2.6 millimeters slimmer than the Nintendo DS Lite, but Nintendo had to sacrifice the GBA slot in order to make the Nintendo DSi smaller. The Nintendo DSi has two beautiful 3.25 inch screens and better speakers. The device has a 3 megapixel on the outside and a 0.3 megapixel VGA camera located next to the DSi’s microphone, both have a 640×480 resolution. Thanks to these cameras, the DSi has different camera and audio functions delivering new and innovative gameplay.

There were rumors that the NDSi has two touch-screens, but there’s only one touch screen. Only the bottom screen of the DSi is a touch-screen and can be used for adjusting sound playback, editing pictures and other new features. You can export pictures to your DSi with SD-cards, but the device also has some internal memory for storing apps purchased in the Nintendo DSi Shop. Some of these apps will be free, others will cost 200, 500 or 800 Nintendo Points. Japanese gamers who purchase the Nintendo DSi by March 2010 will receive 1000 Nintendo Points as a gift.

The Nintendo DSi will come out in Japan on November 1st for 18900 Yen. More details to come!
