Probably not, 2014 is simply a stronger year for software releases:
Mario Kart 8 + Smash U + Bayo 2 + Hyrule Warriors + DKC + Captain Toad > Splatoon + Wooly Yoshi + Legend of Zelda + Star Fox + Mario Maker + Xenoblade X in terms of sales potential.
Though it could be close because Wii U will probably get a price drop in 2015 + potential continued momentum from Amiibo.
