DSi Picture Compare
The 3rd version of the DSi with a larger screen and 2 video cameras has been released in Japan and will be made available in Europe and USA later in 2009 (Buy-DSi.com) . Apparently Nintendo has decided to loose the backward compatibilty with GBA in favor adding a SD card for Music and Pictures. How easy or had it will be to emulate the new DSi-only titles remains to be seen, but nearly all DS roms can already be emulated with No$GBA and other Nintendo DS Emulators.
Looking forward to hacked DSi firmware that would enable playing GBA & DSi roms directly form the SD card on DSi.
