XB1 will surpass WiiU by the end of this year (Already done it in shipments after all).
And no, no known Nintendo IP will boost hardware and sustain it, why would it? You've had 2D and 3D Mario, Mario Kart, Donkey Kong, Zelda remake (which would have got some Zelda fans on board at least), Wii Fit, Wii Music and it's about to get Smash, all that and it'll be around 10m after 2 years which included 3 holiday seasons.
Mainline Zelda and a Metroid along with a load of niche IP isn't going to change its fortunes.
