OK, this isn't drama class people. Iwata passes away, someone asks who's going to replace him and people are over dramatic about some random person over the internet like its this big problem. Nintendo themselves have already thought about it, so why moan and wine about a random thread. Why are people playing the victim card and the hero card? I would guess that you guys care more about your words than you do about Iwata's passing otherwise you wouldn't be constantly bumping a thread with any sort of response what-so-ever.
I feel bad for all of his friends and family, the people he worked with, the people who knew him as in the people who will actually miss more than just his work.
