It might still be too early to call, so I'm definitely jumping the gun. Hypothetical though, which version will you be buying if there is a dual release? Will you buy a NX and get the game for NX, or the Wii U version?
PLEASE release it on the Wii U!!! I love Mario Kart 8 and Splatoon but I mainly bought a Wii U for the new Zelda game!!! I'd be fine with a dual release. It worked with TP in the GC and Wii.
