I could see Nintendo going either way on this...the price has to be low to capture the nongamer market, but two controllers does seem to be in the spirit Nintendo is going for.
Frankly, I think the reason Nintendo hasn't announced the price is because they haven't decided yet. Just like us, Nintendo's marketing and executive groups are probably tossing around various bundles and prices and thinking about what will grab consumers. It probably also depends on how Nintendo envisions the expansion of the market happening. You could argue that, even with a low price point, non gamers won't be interested until they get to play the system at a store, a fair, or a friend's home. That could be months after the launch. If you go this route, it makes sense to sell it with multiple controllers so the hardcore gamers can play with the non-gamers and catch their interest.
I like Iwata's comments on the PS3 controller, and I totally agree: it isn't really a threat because Nintendo's controller was designed from the ground up for playing motion-based games. It would be impossible to perfectly emulate the Wii versions of Wii sports, Mario Galaxy, Red Steel, Wario Ware and Madden on the PS3 controller.
