Have you considered that when we look at the wii u's problems, we're using hindsight bias. It's easy to say they should've known, but the fact is they couldn't of. As I pointed out, console development takes a while. Hell, it's even possible they were too far gone with the wii u by the time smartphones really became a major force that they really couldn't change their plan without wasting a ton of time and money to build another new console from the ground up. The Wii U had problems, but it's a lot harder to spot problems of something that hasn't been released as opposed to something you know has done poorly. And no, all the gamer's who say "I've been pointing out this stuff the whole time", do not mean it was predictable. I remember when the Wii came out, most of the developers and interviews I saw predicted it would fail as well. And a ton of super hardcore internet forum types were already bitter about the wii, and pretty much wanted the Wii U to fail. Bias colored their perceptions, even if they may have been right in the end
