Very sad, and not alot of people knew he was that sick. I knew he missed E3 last year due to an illness, but who knew it was this severe.
Some say he may have driven Nintendo into the state it's in now, I say he was one of the greatest minds in the business and took calculated risks. Who knows which direction the company goes now and who takes over, that is one difficult man to try and fill-in for. Sad sad day indeed.
Going around different news and tech sites, and they all have paid some sort of tribute to Iwata, great to see. Sad to say during his last few months on this earth it was him apologizing for the state that Nintendo is in. It will take years down the road, but I think at some point, people will truly appreciate what he did for Nintendo and the gaming industry. The past few years have been a bit rough for Nintendo, but once you look back on it, the man left quite the legacy.
