Note: I am probably the biggest Nintendo apologist I know, and this is not necessarily another "Nintendo is doomed" post.
Shigeru Miyamoto's position in the history of the video games industry has been established for decades at this point. He has had a direct hand in some of the greatest and most influential games ever developed. However, given the measured success of the 3DS, the weakness of the Wii U, and his involvement in fringe projects like Star Fox Guard and the Pikmin short films (to say nothing of project management concerns around the upcoming Legend of Zelda and Star Fox Zero), one could begin to question the wisdom of placing Miyamoto anywhere near a decision making position around future hardware or software. Perhaps recent stock price losses could even be pinned to projects tied directory to Miyamoto. It might also be telling that Nintendo's most recent unqualified success, Splatoon, apparently had little to no involvement from the man.
Have we hit peak Miyamoto?
