I think it's fair to say that there are some Wii owners who are bringing down the Wii's attach rate because they only play WiiSports.
However, that won't matter in the long term. When the Wii gets to be easier to find, Nintendo will start picking up the hardcore gamers who aren't already onboard. If they cut it to $150, it'll be really hard for gamers with money to burn to pass it up.
By the end of this generation, the Wii is going to be the common denominator of gaming. I predict that most PC, 360, and PS3 owners will end up picking one up at some point. Maybe not in 2008, but some time. And some of the WiiSports players will be adventurous and try new things.
