F-Zero for Wii U above everything else!
3DS basically don't need another racer than Mario Kart 7, and Wii U need all help it can get
Seriously though, if there's anything F-Zero always needed then it's graphics and online capabilities. While a 3D experience at over 1000 km/h would be sweet, it would lack everything else that limits the 3DS.
As for Star Fox, I'd personally prefer another Star Fox Adventures game for any of the two consoles. Way more flight sequences would be appreciated though.
Metroid will probably return for both consoles no matter what.
