if accurate that's pretty incredible and a good sign for things to come. Generally systems 2nd and third years are bigger than their first, naturally as the library builds up and more people feel comfortable leaving their old system behind and becoming adopters.
Keep on killing it Nintendo. I'm fairly hyped for a new Nintendo Direct and the announcements that might come. Have to imagine Nintendo will have some big titles to announce as A) they'll want to continue momentum, B) hardly anything 'big' has been announced offiicially for 2018 from them, and C) those last 2 years of basically absent Wii U development had to have been a lot of games in the works either for the Switch or Wii U games that got translated
