They really need to provide some solid release dates, we know the games are comming but WHEN is a very critical question.
Give dates to the things already annonced, Pikmin 3, The Wonderful 101, Wii Fit U, Game & Wario, and provide months/windows for the things that are a little far ahead Bayonetta 2, Yoshi, X, and Wii U Party.
Then they can wait till E3 to announce/show the other games Mario Kart, 3D Mario, WW remake and some surprise.
