again logic, big games are shown at least 1 year before they are released.

That's not always the case. Besides, Mario Kart and WindWaker were teased on Nintendo Direct a few day's ago. Mario Kart is said to be playable at E3. That means there is a possibility of it coming out this year.

Plus, their is Wii Fit U. That should grab a few casuals.
