It will be lucky to make it to 15 million, as of this moment. All ninty fans bought the console when Mario Kart came out and so that is why SSB didn't boost sales so much. It's a dead console and news on an upcoming ninty next gen console are just helping it drown faster.W

what upcoming console? did i miss something
