In light of that sad, shocking news, I decided to move things around a bit and instead publish this too-brief post about the man who has, along with Shigeru Miyamoto, personified Nintendo for the last 10 to 15 years.
All that's known about Iwata's untimely passing at the moment is what the company shared in a simple note on its Japanese website last night:

"Nintendo Co., Ltd. deeply regrets to announce that President Satoru Iwata passed away on July 11, 2015 due to a bile duct growth."
Iwata's career in the gaming world began long before he took the reins at Nintendo, of course. First he worked for HAL Laboratory and helped produce titles like Balloon Fight, Hoshi no Kirby (Kirby's Adventure) and EarthBound.

In 1993, 10 years after Iwata started at the Tokyo-based Nintendo affiliate, he was named its president.
Seven years later, he joined Nintendo to head up its corporate planning division, and in 2002, Iwata succeeded Hiroshi Yamauchi in the company's corner office.
With all of that said, I'd just like to reiterate the message that makes up this post's headline: rest in peace, Mr. Iwata. You will be missed, and you will be remembered.
