I think a better title for this thread should be "which WiiU titles will be successful and which ones won't", because that's the attitude I'm going to bring to my answer here:
Successful:
Mario U, NintendoLand, ZombiU, Assassin's Creed 3 (it's among the top ordered titles), Call of Duty II, Scribblenauts Umlimited, Just Dance 4, EM2, Rabbids Land
Modestly successful:
NG 3, Sonic, Tekken 2, SING Party, ESPN, Darksiders II, Batman (depends),
Unsuccessful:
Mass Effect 3 (probably, unless EA has low expectations for it), Tank Tank Tank
