Gamecube actually didnt do too horrible in N. America but I think Wii U will end up on top. A price cut sometime around Aug/Sept to $249.99/279.99 alongside Pikmin 3, Wii Party/Fit, Wind Waker should give a good boost going into the holidays then have Basic+Wii Fit/Balance Board and Deluxe+Mario Kart bundles for $299.99 ready in time for black friday. Keep the momentum going in 2014 with 3D Mario in Q1, Smash Bros Q2, Metroid Q3, Zelda Q4 and gmames like X, Batonetta 2, Yarn Yosh, FExSMT mixed in as well. 2015 could get games like F-Zero, Star Fox, Animal Crossing then a price drop to $199.99 with New Super Mario World and Nintnedo Land 2. 2016 is when i see Wii U slaes decline but still solid thanks to Donkey Kong, Kirby, open world western RPG by Retro, after that Nintnedo begins to focus on console/handheld hybrid "3rd pillar".
As far as 3rd party support goes, I think Ubisoft/Activision/EA(will come around once sales pick up) will support it with cross-gen multiplats thru 2015 and japanese devs like Capcom/Namco/Square will give it solid multiplat and exclusive supprot thru 2015. Overall I predict about 40-50 million Wii U sold and 20-25% market share.
