I can't imagine why anyone would be disappointed.
There was a Wii U Metriod game...kinda.
There was a Wii U Animal Crossing...kinda.
There was a release date for XCX...in December.
They're finally doing something substantial with Amiibos...in Skylanders.
Really, the only thing that disappointed me personally was the new 3DS Zelda game. A co-op Zelda game in 2016, where you can team up as Link and...Link...and Link. Because Hyrule Warriors showed that no one has any interest in playing characters other than Link...
I believe in honesty, civility, generosity, practicality, and impartiality.
