This supposedly reliable source claims that Wii U will get "c'est un jeu par mois pour BigN" = it's one game a month for the big N.:

For 2014 - 2015 all games on the list are confirmed or existing (in Japan) except for Okami and RE4. RE4 is coming to other platforms and Okami hopefully could be remastered from the Wii version.

For 2016 to 2018 it is more of a fantasy guess with available Nintendo IPs that has not yet been utilized.

This list started out as an attempt to see how long Wii U could survive without 3rd Party support.

EDIT: $ Confirmed

EDIT:  ^ Moved the game in the release schedule from its original place.

EDIT:  * Added third-parties that already exist but only in Japan

EDIT:  ** Added Diddy Kong Racing 2 according to this rumor: https://kevincallahangames.wordpress.com/2014/07/09/the-strange-development-of-diddy-kong-racing-2/

EDIT: **** Added games confirmed by NOA:  https://mobile.twitter.com/NintendoAmerica/status/506487150125535235/photo/1

I know I am rehasing an old thread:

Shit! I don't want to wait until early 2017 for a Paper Mario game that may or may not turn out to be much better than Sticker Star!

I'd like to see how a Rhythm Heaven game would work out on Wii U!

haha, "the big n" ... that could go so wrong so fast in the wrong hands.

nice dream.

The first year seems possible. After that everything else is guesswork, so let's see

The source was only talking about 2015. They could do that.

Devils Third will likely be late 2014-early 2015 and I see Splatoon taking MK8's spot in 2015 and I doubt FF would release in the middle of summer:

2015 January: -Mario vs Donkey Kong
2015 February: - Yoshis Wooly World
2015: March - Devil's Third
2015: April - Mario Maker
2015: May - X
2015: June - Splatoon
2015: July - Majora's Mask U
2015: August - Kirby
2015: September: - Mario Party 10
2015: October: Fatal Frame
2015: November: - Zelda U
2015: December: - SMT x Fire Emblem

2016 onwards looks ridiculous, IMO. SUPER wishful

I was hoping for a summer Fatal Frame Horror Movie US release. Splatoon will probably not be Q1 as promised. Is May a good month for X? I put Devil's Third in early autumn because that is where Nintendo tends to place their "experiments": W101 and HW.
