In many ways I believe that Kutaragi was a man who was in the right place at the right time, became remarkably successful, and was given an (undeserved) reputation as being a visionary ... He (unfortuately) believed the hype surrounding himself and allowed it to go to his head.
In contrast, Iwata took control of a company at a time when most people thought it was doomed because it was facing new competition in its most profitable segment (handhelds) and few people thought it could compete directly with Sony and Microsoft in the home console market. He brought the company to success by breaking from conventional wisdom and producing products that were drastically different than what people expected. Iwata is also a very modest man and is not going to fall into the same trap of hubris that other people have.
