Great post. And welcome to the forum.
I agree with your strategy in general, in that Nintendo cannot be complacent and could do a lot more to make money from the existing and new audiences. How would Nintendo produce all of these titles while maintaining the quality we expect? They have about 8 "quality" teams: EAD and Intelligent Systems basically. Each quality game takes 2-3 years to develop, so in any given year you would only expect two or three quality titles split across Wii and DS.
