As if he was responsible for all the bad ways Nintendo acted.
Not enough console power has been a problem since the SNES. The only exception was the GameCube and people didn't give a shit about it. Then they polish it a little and release gimmick controls and, what happens? BOOM! Most successful Nintendo console ever. Same thing with the Nintendo DS, despite being obsolete long before its release.
This gen has been quite obvious about gimmicks: 3D didn't catch up and the Wii U second screen either. This is the only thing that will eventually force the company to another direction, not Iwata's death.
As for region locking, nobody here seems to understand the advantages of it, economically-wise. There aren't enough pros to remove something that helps the company determine sales, especially if I can only think about one game on 3DS that wasn't released outside Japan that I could play without feeling too much confused.
As for the online system, we got a HUGE improvement from the old Nintendo WFC thanks to updates that ban cheats and bug-fixes. We need leaderboards, but how is Iwata responsible for them? Same with 3rd party support. How was Iwata's problem if EA snobs Nintendo consoles when it comes to FIFA?
