Chris Kohler, writing for Wired:

You can attribute the fluctuations to irrational exuberance on the part of investors, as Nintendo doesn’t publish Pokemon Go. It co-owns the rights to the franchise, and holds stakes in Go publishers Niantic and The Pokemon Company, so it is surely making some money from Go. But nobody knows how much. More to the point, Nintendo didn’t create the game, and so its existence doesn’t suggest that Nintendo’s management finally “gets it.”

I think this piece paints a gloomier picture of Nintendo’s future than I’d prefer. But I agree that we shouldn’t be treating Pokémon Go as the beginning of Nintendo truly understanding the mobile marketplace. The reality is that Nintendo had little —likely zero — to do with Pokémon Go’s development. My assumption is that this the game’s success will teach them that it’s okay to release some of their franchise games on iOS and Android, but I don’t expect the flood gates to open just yet. Things will probably get a lot worse before they get better.
