no by my logic you compare the games at the end of the life cycle of the console so that they are comparable.
I do think motorstorm sold better due to the absence of GT5 and such games, when the PS3 will have sold 40M it will look a lot worse than now.
say the wii sells 120 M then motorstorm would have to be multiplied by 3 to compare (so it would equate to a 10M selling game on wii, but by the time wii reaches these numbers, all the games you cited will be above this...)
I repeat: compare at end of life cycle.
