Nintendo has a long history of taking hardware risks that are targeted at actually making interesting new types of gameplay possible. The richness of games available would not be possible if Nintendo was not in the picture as a hardware manufacturer and had to target all their games at MS/Sony hardware. Sony & MS have almost never tried any novel hardware and been able to tie it to unique gameplay that was actually successful. They've only tried to copy Nintendo's ideas, mostly failed, and then cancelled the hardware. See Kinect, Playstation Move controllers for PS3, etc.. it was all just copying the Wii. A lot of the games on DS and 3DS would never have seen the light of day with their unique gameplay elements without Nintendo doing the experimental hardware required.
