As long as the power is up to par or beyond, with a traditional controller available on the side (must properly host 3rd parties), I'm not opposed to Nintendo having a unique interface. Nintendo just has to make sure its fun, able to revisit over and over, and cater to most genres. MSony are the established, "serious" consoles. Nintendo should act like the other two as a basis, but IMO must also introduce a fresh experience for their own games. You can call it, "Wii" (rebranded obviously) with power. This way, they can serve everyone to the meximum (unlike Wii U, who tried to serve everyone at the minimum).
And now culturally, take the Splatoon example. This will be tough for the Japanese company to swallow, but follow the youthful minds, and push the geriatrics to the business side and away from game & hw design.
That's my solution = If you build it, they will come. No real need to buy any exclusives or flailing studios.
