According to Official Nintendo Magazine in the UK, a brand new Wii U game is supposed to be shown in their April issue. They have said it won't be StarFox or F-Zero unfortunately, perhaps it's a new Metroid though.
I still hope it's Metroid then. But it likely won't be a big game if it's going to be revealed in a magazine.
