I would love for Wii U to have a consistent flow of exclusive software throughout 2015 but after seeing the software output in 2013/2014 and so many delays/droughts, I'm not going to get my hopes up.
this is what I would like to see
Q1-Yoshi's Woolly World+Monster Hunter 4 Ultimate
Q2-Mario Maker+Splatoon
Q3-Super Mario Sunshine HD+Xenoblade Chronicles+Star Fox
Q4-Devil's 3rd+Kirby Rainbow Curse+Mario Party 10+Fatal Frame 5+Legend of Zelda
but I wouldn't be surprised to see this
February-Captian Toad:Treasure Tracker
May-Mario Maker
August-Yoshi's Woolly World
September-Splatoon
October-Devil's Third
November-Super Mario Sunshine HD
December-Kirby Rainbow Curse+Xenoblade Chronicles X (Japan only)
Star Fox gets pushed back because of never was really planned for 2015, Mario Party 10 is purposely delayed to fill in the Q1 gap, Zelda isn't ready and becomes the holiday 2016 title, Monster Hunter 4 Ultimate never comes to Wii U, and Fatal Frame V never gets localized.
those are pretty much my best & worst case scenarios, I'm expecting something in the middle.
