Diancie has been officially revealed for North America. Within this reveal, it was confirmed that it will be within the new movie and that its distribution method will be revealed at a later point. It also states that it was a sudden transformation of the Pokémon Carbink, and that its body is said to be the loveliest sight in the world. Groups of Carbink tend to gather around Diancie, but Diancie pays them little heed and acts only according to its own will.
They also inadvertently revealed the shiny form of Diancie on the official site, where it has darker rocks and a pink body.
