You cannot say that Wii owners don't like FPS, they dont simply get enough choice the only decent FPS games are: RS (which sold well despite its flaws) and MOHH2. MP3 is not really a typical shooter.
On rail shooters sell extremely well on Wii: RE:UC, Ghost Squad or House of Dead (considering age of last two)
I know there are possible more FPS and shooters fans on the other consoles but i dont think difference would be that big if there was enough choice for the Wii owners.
