The casual gamer that people think about does not exist. Anyway the Switch is a Blue Ocean product. It is not directly competing with anyone. In the handheld realm there is no one to compete with! Also look at NIntendo's games. Splatoon is a shoot but it is unlike any shooter I ever played. Arms is a fighter bub it is unlike any other fighter out there today. Mario Kart is nothing like most best selling racers. The Switch has both Blue Ocean games and hardware.
Hopefully Nintendo never goes for the hardcore gamer ever again or it will be the Wii U all over again.
