What directions are you thinking about, exactly? Because as you yourself remarked even WiiSports has the form of a game. An accessible one with a low entry barrier, but still a game.
WiiFit now is a different beast because the main appeal for customers doesn't seem to come from the experience vs goal focus shift, but from the fact that it is a friendly fitness experience.
Maybe that was what puzzled the designers about the public reception of WiiMusic: they could have misinterpreted the success of WiiFit, lending more importance to its form than its specifics.
