During last night's Game Awards 2014, there was a special segment where Mr. Miyamoto and Eiji Aonuma showed off a lot of gameplay footage from the massive open world of The Legend of Zelda Wii U. You should watch the whole thing, because it's amazing!
During their conversation, however, Mr. Aonuma asked Mr. Miyamoto how Star Fox Wii U was coming along. Mr. Miyamoto replied that Star Fox development was coming along well. He said that the game's use of the Wii U gamepad really feels right, and that the game should launch before the new Legend of Zelda Wii U game. You can hear that part of the conversation at 3:18.
Thanks to Dogman15 and Kevin for the heads up!
