I picked option 3, but really a cross between several of those things: especially option 2 and 3 while maintaining option 1.
But I think option 2 should only happen if they're inspired, the whole idea of the Gamepad seemed very short sighted compared to the Wii Remotes/motion controls and Hybrid play. of course, they should only add in the new tech if they can carry it in their hardware indefinitely, because I want all games to be playable on future hardware, not just some! ALL games that have ever been on Nintendo hardware in the past, along with a fair chunk of Sega/Sony/MS/Apple/Steam games.
I describe myself as a little dose of toxic masculinity.
