We have seen patents from Nintendo that showed the switchable controllers on a screen years ago.

the patens went public august 2016 lol :D

They have several patents and the fact that they were granted in the first place supports the point. WiiU prototypes, which means pre 2012 alone makes clear that Nintendo had this idea a few years ago.
