I think Nintendo should just continue making the games they make, *though* I would add with the caveat in the 90s they did quite well having a mix of Western and Japanese games (Perfect Dark, Conker, Killer Instinct, Star Wars, Ken Griffey Jr. MLB, Kobe Bryant NBA Courtside, Starcraft 64, Banjo-Kazooie, GoldenEye, Jet Force Gemini, etc.).
I think I would implore them to not make the NX too toy-like. Make the same games, but keep the platform almost separate from the games, in the sense that the NX shouldn't be a "Mario box".
One of the problems I think Nintendo is running into is they're too prone to their toy-roots and are making toy-like game machines, and that just doesn't fly in this day and age. Keep the games the same, but "NX" I think it would be better for Nintendo if it was almost like a third-party platform (of course Nintendo still makes it) that just happened to have all the Nintendo games as an exclusive.
