A Star Fox!
An article on Time.com describes Miyamoto's "smaller, personal projects," which include a new Star Fox title, and two new games that are exploring different uses of the Game Pad:
In one of the games, which Miyamoto called Project Giant Robot, players control sky-scraping automatons, angling the Wii U GamePad in front of a TV screen while shifting their torsos left and right or up and down to maneuver the robot's upper-body while thumbing the controller's joysticks to punch or grab — almost like a full-body game of Rock 'Em Sock 'Em Robots.
In another, titled Project Guard, the GamePad became a quick-jump map of a fortress manned by numbered, laser-firing security cameras. As robots encroach on different entry points, you have to tap the GamePad to leap from camera to camera, blasting enemies that trundle or come at you sprinting — even some that sneak under your radar.
