I don't believe Star Fox will be ready for next year, and if I were Nintendo I would delay Mario Party to make it an online multiplayer game.
I think next year we will have Yoshi, Splatoon, Devil's Third, Mario Maker, Mario vs Donkey Kong, Kirby, Xenoblade, Zelda, Mario Party and some HD gamecube game, like Sunshine HD. And perhaps Shin Megami Tensei x Fire Emblem.
2016 Star Fox, Pokken Fighters, perhaps Wii U Metroid or Animal Crossing, some smaller title like a Mario Strikers or Punch Out.
and in 2017 the new console.
I don't see how anyone can found Wii U's 2014 to be disappointing. Few games, but Donkey Kong Tropical Freeze, Mario Kart 8, Batonetta 2 (+1), and Smash Bros are really great exclusives.
