LKS is just a game a game that contrasts with current trends in Gaming industry its not "bigger, better and more badass" with uber realistic graphics and teh cell enabled physics.
Games that tend to sell well are big blockbusters with a lot of explosions and budgets, just like in the box office a bellow average movie like Transformers 2 will do well because of effects.
Wii owners might be different then 360/PS3 in terms of their taste but LKS is just too much of a niche game to sell well.
