In an interview with Polygon, Nintendo’s General Manager of Entertainment Planning and Development – Shinya Takashi – may be hinting an an upcoming smartphone controller to be used with Nintendo’s future mobile offerings.

Physical controllers for smart device applications are available in the market and it is possible that we may also develop something new by ourselves.

Takashi’s comments come just before Nintendo is to release its first peripheral-based mobile title, Pokemon Go. The augmented reality experience is free to play but can be enriched with the purchase of the Pokemon Go Plus wristband.

In a way, the wristband could be Nintendo’s way of testing the waters to see what percentage of its mobile customers may be interested in purchasing a peripheral to add to their experience in the game. Although we’re likely far off from a Nintendo mobile title requiring a physical controller, it’s clear that the software giant will be taking its mobile business seriously over the next few years.
