Bile duct growth.How did he die?
If it's not too much trouble could you do my avatar? And if it's not too hard could you place the Iwata ribbon in place of my character's bow tie?
My guess is he stopped fighting it. The general beat up worn out look for cancer patents comes from the chemo and radiation treatments.
Could you do mine as well Kriken?
What an utterly unique man as an industry executive. Out of all of the big players, the EAs and Activisions and Microsofts and Square Enixes, Iwata was the man at the top of a titan that most genuinely cared not just about games, and not just about playing games, but about making games. Its not just that he came from a programming background. He was in the business of making games because he genuinely loved the work his company did. That's not something you often get at the very top of the company.
Judging by the press release in the OP, it looks like Genyo Takeda is now president of Nintendo. I don't know anything about him, though.
