Not necessarily. I'm sure some bright spark can come up with an imaginative use for them in a future game or channel.
It sounds like it's going to be a Wii version of "Am I Hot Or Not?" to me. However, if Nintendo expect it to hold our interest for more than 5 seconds, they'll need to allow us considerably more options to customise our Miis - else they're largely going to look the same.
