i heard that the nintendo ds is not meant to be the replacement for the gameboy system, but just a alternate handheld of nintendo. there are a few signs for that, for example a official statement of nintendo at the release in which they demented this fact, an other example is that the ds is not listet in the gameboy line of wikipedia, but in en alternativ article for ds. so will nintento release new gameboy models paralell to the nintendo ds development? or did the original gameboy concept die out in the end? how could a new gameboy be designed and featured to be lucrative next to the profitable nintendo ds system?
