Well it's obviously a Wii U game, and it's probably a new Metroid game. But I would also put my money on it maybe being a new F-Zero, although I would have thought Sega would be on board for that. But seeing as Naughty Dog and Vigil games are known for third person action games, my money is on a Metroid game in the style of Uncharted, cinematic third person moving away from the prime first person games.
Asked them to make Kinect games
Awesome now I don't have to buy a new PC :p
