If I am not mistaken, this is going to be the third refresh for the DS. Nintendo has announced DSi which will look like the DS but with some changes. Engadget
has the photos and the details. The DSi is going to be thinner because the GBA slot will be gone but the screens get a little bit bigger. The biggest additions though are a .3 megapixel camera on the back and a small camera on the hinge's front when you open the DSi up. It has an SD slot and from the video it looks like you can plug in something for the excercise game. My guess is that it's a pedometer. The DSi is expected to be launched in Japan in November and the rest of the world next year and it will come in black or white.
