It seems Miyamoto isn't going anywhere after all.
In an Reuters Japan article, Nintendo has clarified that the game designer isn't stepping down from his position at Nintendo.
"This is absolutely not true," said a spokeswoman for Nintendo. "There seems to have been a misunderstanding. He has said all along that he wants to train the younger generation. He has no intention of stepping down. Please do not be concerned."
It was originally reported in a Wired interview that Miyamoto was stepping down from his position at Nintendo to work at smaller projects that would take less time to make.
