You mean a two-year-old, second-rate port didn't expand the Wii's core market? Gasp! Shock!
I think the sales of Silent Hill: Shattered Memories are more telling. That game pulled 100k in America in three weeks, while its sister game (Homecoming) sold only 200k lifetime in the same territory on the 360. And Shattered Memories is even more of a niche title than Homecoming.
It's said in every thread like this, so I'll say it here first: Core games sell on the Wii if they're what the core market wants. The core market doesn't want more rail shooters or half-arsed ports; it wants games like SH:SM.
"'Casual games' are something the 'Game Industry' invented to explain away the Wii success instead of actually listening or looking at what Nintendo did. There is no 'casual strategy' from Nintendo. 'Accessible strategy', yes, but ‘casual gamers’ is just the 'Game Industry''s polite way of saying what they feel: 'retarded gamers'."
