Iwata. The opinions about this man have been mixed.
He is the man that took a company that was leading the "omg look at these graphics" philosophy on making consoles that Nintendo had with the NES,SNES,N64 and Gamecube,and turned it to "lets keep graphics old but try something nobody would expect" philosophy that Wii and WiiU were designed on.
Iwata's strategy worked well with the Wii,as it sold quite good. But now it didn't work with the WiiU.
Perhaps if the gimmick / special feature of WiiU was more catchy,it would have sold way better.
But as it is now,having an extra sceen on the gamepad didn't turned to be that attractive.
The problem with Nintendo has been that they always needed to be first on sales to not consider their consoles failures.
Even if a console would bring in profit,if it was not the one that would sell most,they wouldn't feel good with it.
Take Gamecube for example. A great console.
While it finished third on the race of sales between PS2 and Xbox,Nintendo was getting profit from each console did while the others was loosing money and expected to get them back from software sales.
That brought Nintendo much more capital profits than the others did from hardware sales actually:
Yet Nintendo wasn't pleased,and Iwata decided that not only each console should bring profit,but also that the number of console sales should be the highest than the others,so he made Wii,which skyrocketed Nintendo's income.
From a business perspective Iwata's movement have been more than successful: He doubled Nintendo's profits.
Yet while with the Wii Nintendo got richer than ever,quite a number of people who were buying Nintendo consoles were displeased,because Nintendo catered to a different audience.
The problem with WiiU is that it is a product that doesn't seem attractive neither to the 'core' gaming audience,neither to the 'other' audience.
And while practically WiiU is a failure for that reason,what Iwata has already offered to the Investors (double the earnings) is quite a good job.
If action is to be taken,then I don't think it will be Iwata loosing his job.
It's much more plausible to stop the production of WiiU next year and come up with another console and Iwata in his position,than firing Iwata.
Because while Iwata did a mistake with WiiU,he did a great right with Wii,at least in the Investor's eyes.
How Iwata manages WiiU's bad sales is remaining to be seen,and remember: This is the second console Nintendo releases with Iwata in his position,and the first to fail.
I'm sure they will give that guy another opportunity.
Now while as an Investor I would personally give Iwata a second chance,as a gamer I preferred the old Nintendo philosophy,the one of leading the hardware race as it did in the NES-SNES-N64 era.
