Not really, they tossed out some vague rhetoric, but it was obvious from their actions they had moved beyond the expanded audience.
First clue was the system itself, especially the gamepad, its big clunky and uneccesary.
Second is the library especially the rehash NSMB Wii U and the shallow Nintendoland, which showed Nintendo was not interested in really reaching out to an expanded audience like they did with the Wii
Just because they did it wrong doesn't mean they weren't trying to.
They knew the casuals had moved to tablets, so the gamepad was an obvious attempt at getting their attention back by having a similar device. Nintendo Land was an attempt at recreating the Wii Sports effect, while NSMBU was only the newest in a franchise that has always sold countless millions to casuals. They were 100% committed to bringing back the casuals for the Wii U, but they failed because the casuals were obviously not willing to pay $300 to play $60 games when they already have a tablet filled with free to play stuff.
No, they moved to tablets because Miyamoto has long wanted to seperate the system from the TV, he had talked about that idea for years.
Wrong, it had nothing to do with paying for $60 games or paying $300, if the games had been compelling, and on good hardware, people would have wanted it.
But the gamepad is not a good device for games, nor is Nintendoland anything like Wii sports, its a bunch of nintento themed mini-games, not a sports based game with no real nintendo theme.
Sports games have much more appeal than minigames and the Nintendo theme was not what the expanded audience wanted.
As for NSMB WiiU, it was a rehash of NSMB Wii which itself was not anything new or special (NSMB wii succeeded because people had been hungry for a 2D mario, after that hunger was somewhat satiated, Nintendo had to be innovative with the next one they failed), where was the interesting worlds to explore, the wide assortment of playable characters and the great music.
It wasn't there, it was clear that Nintendo wasn't interested in reaching the expanded audience, and the words for people such as Miyamoto have confirmed this. They want to make what they want to make, not what the expanded audience wants.
