My understanding from what Lucas has said is the Dark Side actually should not exist. The Dark Side is a perversion of the Force. Think of a lake which is serene, calm, but you throw a rock into it and it causes ripples ... the ripples are the Dark Side.
So "balance of the Force" I believe is the complete destruction of all Sith as it restores natural harmony to the Force which is supposed to be all light.
