What do you think Retro is doing?

[S.Peelman]

Didn't they already say Retro isn't making any new Metroid game somewhere?

My guess is StarFox though, which would be awesome, because it's the most likely guess. F-Zero is out because Miyamoto didn't want another of those, Zelda is out because that's still exclusively with the Zelda team and Donkey Kong is out because I'm still betting the next DKC will be on 3DS.

They could also be making the new Yoshi's Island game which is rumored, but I doubt it because that wouldn't be 'hardcore' enough for the image of the studio.
