| Wii Sports has an almost 1:1 ratio of sales to the Wii in Japan. In contrast Zelda has what? 600K in Japan? Miyamoto even said he was disappointed in Zelda's sales.
It's not about it strong-arming other genres out of the picture on the Wii - you did not understand the point.
The point is that only some of the audience are people like you and me that buy games like Zelda. The majority are a completely new set of people who have not been interested in what was previously available.
That's why you'll see the majority of your "hardcore" RPGs like Blue Dragon and The Last Remnant on the X360 - because it's going to be an audience comprised of far more people who will buy that style of game.
