Enric Álvarez: Of course we've thought of making Metroid 3DS... and that's all I can say (laughs).

We had a really nice breakfast-chat (2h+) with Mercury Steam team yesterday in Madrid, mostly (and naturally) about the great (IMO) Castlevania LoS: Mirror of Fate. Game director is a huge Metroid fan, and franchise was mentioned several times. Also, his most anticipated game is actually Metroid Wii U.
So we found it rather obvious: Metroid fan, best sample of what a studio can do with the genre on a 3DS, Nintendo now more open to IPs outsourcing... Asked if they had pitched anything already, but that was the only answer.
So, I know there has been some controversy on Mirror's design decisions, but I honestly think they could actually find the sweet point between 3D design and 2D action/exploration for the series. What do you guys think?
