No matter what, no company can have a solid release schedule without third party support. Can you say that Nintendo should be actively pursuing 3rd parties more strongly? I don't know, and neither does anyone but the people directly involved in those companies. I feel like Nintendo gave 3rd parties something they could use with the Wii U but eveen still, there were an abundance of "its just not feasible for us right now" or "we want to do something more with the Gamepad". Who do you blame for this? Nintendo for making unique hardware or third parties for shafting Nintendo before they give it a chance? This is up for debate.
Is Iwata the problem though? I would say no. Not because he is perfect or doesn't make mistakes but because he keeps the company true to itself. The one thing I can rely on as long as Iwata is president of Nintendo is that they will keep making great games like you can find nowhere else in gaming. With so many others adapting to the norm, I think its healthy for the industry to see someone doing something different and taking risks, not all of which work out.
