This year still isn't that bad even without Zelda.
This is the Wii's 2009 (it's equivalent year to the Wii U's 2015) in terms of new games:
New Super Mario Bros. Wii
Wii Sports Resort
Wii Fit Plus
Excitebots (NA Only)
Punch-Out!
Another Code (EU and JPN only)
Wii U (2015)
Kirby Rainbow Curse
Mario Party 10
Splatoon
Xenoblade X
Yoshi's Wooly World
Devil's Third
Mario Maker
Project: Giant Robot
Star Fox U
This is assuming nothing new is shown at E3 and pushed into the fall window (I suspect an Amiibo centric title is coming).
