What a sad day not only for Nintendo but for the gaming industry as a whole. One of my favorite quotes from him was when he said that his business card has him as a CEO, he feels more like a developer, but in his heart he is a gamer. I wish more presidents of gaming companies had the same approach. The industry would benefit from it.
Maybe not everyone agreed with his choices, but he has left a positive mark on the industry. He will be missed and whoever becomes the next president has some big shoes to fill. It's hard to think of anyone being funner to watch when they bring Nintendo Direct, "direct to you!"
That being said, it will be interesting to see who takes over. I know for now Shigeru Miyamaoto and Genyo Takeda will take over until they find a permanent replacement as they are both senior managers. I know there has been talks of Miyamaoto doing it, but at the age of 62, and already looking to lighten his load, I think Nintendo is looking elsewhere.
