Nintendo is far behind being irrelevant in the home console business.
You become irrelevant when despite the good decisions you make, you still don`t attract gamers.
Wii U failed not because gamers don`t want it, Wii U failed because Nintendo failed in selling it.
Which is nothing new in the business and we have more than a few success stories of people who turned around their bad start.
And somehow people keep forgetting that. It`s like history teaches them nothing.
