I really hope they call it Faerie type rather than Fairy. Fairy has some real connotations. I'd struggle to take a non-pink-and-cutesy Fairy type properly, and I'd be really irritated if every single member of the Fairy type was girlish and cutesy.
Faerie would at least embrace the mythological and mystical aspect of such a type.
I'd rather they just called it Light instead though.
