Well every game I've had issues with in the past where on 100% "N" created devices/hardware, so if that is their plan, it's a rather poor one. I have found motion controls usable in some situations, but I have never had 100% accuracy, and for me, that is a broken control option. And with no other choices, your stuck playing games that are more work dealing with the controls, than actually playing and enjoying the game.. If I'm using a standard controller, and something goes wrong, it's human error. With motion controls, when things don't work as they should, it can be a combination of so many things, it just becomes frustrating, more than any level of fun that should be had.

In my experience, motion controls have to be done very right to not detract from the game. Aiming in Metroid Prime 3 and Resident Evil 4 on the Wii, gyro-supported aiming on the Steam Controller and the few VR games I have played on a friend's HTC Vive are examples that worked very well for me.
Doesn't BotW do gyro-aiming on the Wii U tablet controller? I remember that working okay for me, better than stick-only aiming...
