One point that has not been addressed is that sharing the library between a handheld and a home console is not the same thing as sharing the library between a smartphone and a tablet, since smartphone and tablet hardware are very similar.
Sharing the same library between a handheld and a console would be similar to sharing the same app library between a smartphone and a PC or Notebook. As far as I know, every attempt of making consoles that play mobile games or computers that working with mobile OSs didn't work very well.
My feeling is that Nintendo is not looking for being able to produce more games. They are going after insane hardware sales of iPhone, iPad and Samsung smartphones. Their new architecture would be more to support lots of hardware iterations without having to worry about developing specific games for each platform. They probably are looking for something like a n3DS every year. The objective of n3DS is clearly selling hardware, and that is probably their focus in the following years.
I am not sure if that strategy will work well with machines dedicated to games, but that is probably their bet.
