Nintendo announced Thursday the Nintendo DSi at their autumn conference in Japan. Announced as a “third platform”, it appears as if the DSi will supplement and not replace Nintendo’s current lineup. The DSi will be 12% slimmer than the current DS Lite and will have slightly larger 3.25″ screens. The handheld will incorporate dual cameras, a 3MP on the outside and an internal one on the inside hinge. The new model will also sport a SD card slot, new music software, a built-in web browser and support for a new “DSi shop” to download games and other DSi software over WiFi. The new shop will accept Nintendo (formerly Wii) Points; 1000 of which will be included for free with the device until March 2010. Missing on the DSi will be the Game Boy Advanced Slot so GBA games are a no go. It will be available in white and black starting November 1st in Japan for ¥189,000 (approx. US $179).
