Retro says Wii U is “a powerhouse”, new game has been in the works for a few months

Well, good; if it's only been in development for a few months, then that means they're not working on Mario Kart 8, but a whole new game. Excellent.

To be honest, I really expect them to do a new Metroid now, considering it would be (relatively) easy to make for them because they made 3 of them before, they stated they like working on that franchise, and Miyamoto himself said Retro would be a likely candidate for a new Metroid game. Also, Metroid's due a new outing.
