Basically I just saw this as a knee jerk reaction to the delay and the fact that it wasn't a Mario game. I'm also willing to bet dollars to donuts that the people who just left where the ones who only become interested in Nintendo the moment they announced they were stepping into the mobile realm.
Watch, if Miitomo (and by extension Nintendo's other current plans) go smoothly and become successes, they will earn back all they lost and more.
