Nope they wouldn't and I think this is down to something I'm not sure Nintendo can ever recover from, and that's the online communities established to existing franchises. People are unlikely to suddenly start buying such third party franchises on a Nintendo console, even if it's at the start of a new generation, because they've built up communities around certain games on the other consoles for the last 7 years. Everything they ever need for those games is already in place, easy to access, good to go and it's where their friends are.
