I know this was already done, but oh well:
Guesses on release dates (Japan considering the focus of the presentation, though most of these will hold for other regions):
March- Game & Wario
April- Wii Fit U
May- Pikmin 3
June- Wonderful 101
July/August- Wii U Party
Fall- Wind Waker (confirmed)
Fall- Yarn Yoshi (seems like a title they would hold off on revealing if it was too far away- not a major major seller)
November- Super Mario Universe or whatever it is called
December- X
2014- Mario Kart, Smash, Bayo 2 and SMTxFE.
Edit- It wasn't shown but I bet Retro's game is holiday 2013.
No way X or Retro is ready by this holiday. Replace X with Mario Kart.
