I don't see the point in Light type. The Dark type is bad enough as it is, but if there were LIGHT AND DARK types, it would just make Pokémon one of those cliché things where it's all about OH MAI GAWD LIGHTNESS AND DARKNESS AGH SRS BSNSS.
I think a type like Cosmic or Digital would be much more interesting. Although in all honesty I don't think there will be another Type.
