Zelda Wii U: Confirmed to have no release date at this time.
Nintendo has issued a supplementary statement to their 1st fiscal quarter financials which includes the traditional updated release schedule.
Although most of the games were already revealed, Project Guard is now listed as a 2016 elease while Project Giant Robot, which previously listed as 1st half of 2015, is now showing a TBA release date. This confirms that Platinum is working to turn Guard into a full game as was announced at E3.
The other major news is that The Legend of Zelda Wii U, which has not had a release window since March's delay, is still showing "TBD" on the schedule as a result along with the European release of Dr. Kawashima's Devilish Brain Training. However, Zelda Wii U will likely release.
