There are a ton of great games coming out this Q4 2K14 for the 3DS alone, let alone the Wii U.
A few examples of 3DS games this year:
Professor Layton VS. Phoenix Wright Ace Attorney
Fantasy Life
King of Pirates
One Piece: something (LOL, I forgot, but it's on the web)
Rodea the Sky Soldier
Yo-Kai Watch (Youkai Watch in Japan)
Super Smash Bros. Four 3DS (before Wii U)
YuGiOh! 3D (about time)
TheatRhythm Final Fantasy: Curtain Call
And several other 3DS titles.
Anyways, 2015 is the most obvious year for Zelda Majora's Mask 3D, I mean they didn't say anything about out loud, so obviously with all the strong hints that it's coming 2015 with many other 3DS games like Codename S.T.E.A.M Monster Hunter 4 Ultimate & Bravely Second & Yo-Kai Watch & Denpa Men 4. & many other titles releasing in 2015 for 3DS exclusively.
