Nintendo design chief Shigeru Miyamoto has said Retro Studios could one day collaborate with Nintendo on a Legend of Zelda game.
The US studio previously developed the Metroid Prime series and Donkey Kong Country Returns for Nintendo, and most recently collaborated with the platform holder on Mario Kart 7.
Miyamoto told Wired: "As you know, we have already collaborated with Retro for the Metroid Prime series in the past. And I think when we talk about any other franchise, Zelda might be a possible franchise for that collaboration."
According to design legend, Retro was charged with "taking care of the design of [Mario Kart 7's] courses and the artwork", while Nintendo handled "the gameplay and the control mechanism itself".
