My guesses for 2015 (Japan) ...

Feb - Mario Party 10
Mar- Yoshi's Wooly World
Apr- Mario Maker
May- Splatoon
June- Kirby Rainbow Curse
July- Super Mario Galaxy Collection
Aug- Devil's Third
Sept- Xenoblade X
Oct- Star Fox U: Episode I
Nov - Legend of Zelda
Dec - Pokken Fighters

Fixed

I think with a new IP like Splatoon, Nintendo may as well leave it in the oven for a few extra months for quality purposes. 

I guess it does depend though on how Xenoblade is coming along but by May 2015 I'd have to think its been in development for about 3 years.
