I really hope we get like 12 new legendaries in Sun and Moon.
A trio. Psychic, Dark and Fighting maybe. And their leader.
The 2 game mascots plus the third member. Ice type for Moon, Fire type for Sun.
2 random legends. One has to be poison.
3 mythical Pokemon, Magearna being one of them. Something evil like Darkrai or Hoopa Unbound for the 2nd, maybe Dark or Ghost type. Dragon and Fairy for the last one, something mystical, rarest dragon etc.
