Shigeru Miyamoto — creator of Mario, Zelda, Donkey Kong and more, of course — has dropped a seriously big hint we'll see new characters from Nintendo very soon.
The Guardian asked Miyamoto if there was a particular game or style he wanted to work on, to which he replied:
I don't have a big list of ideas I want to realise, I usually come up with new ideas while I am working on other games. That said, there's a strong possibility we will introduce some new characters to the scene soon.
We haven't seen many brand new Nintendo characters in recent years, but with Miyamoto focused on new franchises it probably won't be too long until we see a set of fresh faces.
