The two men are actually extremely different. Cerny and Iwata do have some similarities which the OP pointed out, but think about what these men are fundamentally about. Iwata was CEO of Nintendo. Cerny was never CEO of Sony or even executive over their entertainment division. Cerny lead the hardware development, but not the whole Playstation brand. Cerny is like Sony's Gunpei Yokoi. Yokoi invented key hardware like the Zapper and Gameboy and also was involved in game development (Donkey Kong, Metroid, etc...). Cerny has long been involved in hardware and software development, so Yokoi is a lot more who he is like.
