What allways kills Nintendo is games, I dont care as much for handheld but actual new good projects. And Nintendo allways limited itself by focusing too much on kid nostalgia and old played out franchises rehashed to get with the times. So as genius as this new console looks, it will fall flat if they dont keep up to date with new games like Playstation and Xbox does and give us plenty of options to choose from instead of the same set of limited list of games, or delayed releases etc.
The trailer for the console looks promising on that score, because they showed a range in games to play, mainstream popular games and not just their niche collection.
Also huge plus for the innovative looking controlls.
