Dear lord you're annoying me, Ian.
I think KDR has already said this well, but I think it's worth repeating: targeting everybody (and yes, that's who Nintendo is targeting here. Let's get off this 'non-gamer' buzzword Nintendo has started using for a second.) is not a risky strategy. In fact, it's the only strategy that has ever been truly successful in the marketplace. Everyone played Donkey Kong. Everyone played Nintendo. Everyone plays playstation. Everyone plays GameBoy. ....And no, the "everyone who are gamers" line doesn't fly, because both Sony and especially Nintendo created gamers...they wouldn't have florished if they hadn't.
I'm sorry you feel like, in the past, you were a part of some special group of people who 'got' gaming while the rest of the world was incapable. But Nintendo never made products for a special group. They made games that drew people in who had never been interested in gaming before. They specialised in giving complex experiences through simple and intuitive interfaces that everyone could get into.
The fact is, gaming can be for everybody, just as much as movies can be. I'm sorry you feel that everyone who doesn't game are braindead morons who lack all manner of curiosity and problem-solving skills. Nintendo and I choose to believe that people who don't game might do so for different reasons. Reasons like the fact that modern controllers are about as befuddling to a non-gamer as the controls in the cockpit of an airplane are to a non-pilot.
As Nintendo becomes an increasingly niche company, what would you have them do? 'Try harder' without changing in any signifigant way, I suppose. Personally, I don't think that'll cut it. How do expect Mario and Zelda to compete in the face of Jak and Daxter and Grand Theft Auto? Modern games are huge, violent, expensive. And Nintendo could certainly try to play on that playing field, as you suggest they should. But they aren't interested in that. They're interested in making people interested in the kind of games Nintendo likes. And to to do that, they need to reach out to people in a different way. As other companies make their games more realistic and more complex, Nintendo will blaze a new trail by trying to make their games as fun and accesible as possible. Sorry if you don't want that. Sorry if you want gaming all to yourself.
...Me personally, I want as many people getting interested in Nintendo games as possible.
