Any new Super Mario Galaxy title would be dependent on new Nintendo hardware, says Mario creator Shigero Miyamoto.

"Me and [Yoshiaki] Koizumi-san, director of Galaxy, are always looking to challenge Galaxy and do another 3D action title," Miyamoto told Eurogamer.

Recent Mario games have returned to side-scrollers like New Super Mario Bros or "middle-ground" titles like Super Mario 3D World.

Those titles outsold the open, fully three-dimensional Galaxy series by a factor of more than two to one.

But Miyamoto intimated that with updated hardware, Galaxy could see a return.

"Wii U's definitely good enough in terms of hardware performance, it is more the workload of the team. If you look at Star Fox Zero, the TV and GamePad are both rendered in 60 frames, so in total that's 120 frames. It's really just a matter of the CPU speed at this point."

Nintendo's next-generation NX console is still under wraps, with details to be revealed in 2016.
