You need to be careful with those surveys. Many of those statistics tend to be too inclusive.
Ehh, the Wii numbers are actually from Nintendo themselves.
And they got Club Nintendo surveys for those. That's another thing that Nintendo nailed for years and the competition doesn't seem to grasp it. Instead of online passes and other bullshit, they motivate customers to buy new by offering them exclusive goods (which aren't ripped out content from their games). And they even get accurate customer data out of it. I have no idea why Sony nor Microsoft isn't doing something similar. What Nintendo is doing in that case is pro-customer. What Sony did was totally anti-customer.
Iwatas inability to capitalize and build on the MASSIVE success of the ds and wii is inexcusable. He needs to go
Eh, I think that MASSIVE success of DS + Wii would have never happened without Iwata. Trying something creative is risky and may fail. Wii could have also failed. But I prefer that approach instead of just pulling a walled PC and just releasing a more powerful system every few years.
