That's ridiculous. You're assuming a 100% attach rate for Zelda for core gamers on Wii to make your claims.
Those games are important to the expanded audience for two reasons, because it was never going to enter the lives of the expanded audience unless there were gaming enthusiasts excited about it in the first place, word of mouth is the biggest marketer for Wii and someone had to start that. If XBox fans can't get excited over the X-mote, who are going to be the pioneers?
Secondly, aside from Zelda those games are important because they are in fact emblematic of the new generation. They are "arcade" games. They have the same values as all the "casual" games on Wii, they are pick up and play, social games. I think it's ridiculous to assert that these games are only bought by the core.
The software support is needed because in truth the Blue Ocean is not a bunch of homogeneous soccer moms. They have a wide variety of tastes just like the core market, and a wide variety of games have made million sellers and near million sellers to reflect that.
A game I'm developing with some friends:

It is largely a technical exercise but feedback is appreciated.
