Some Intersting things from this leak apart from the starters final evo:
Rockruff final evo is a werewolf
Alola doesn't have traditional gyms or the Pokémon League, that's your objective, after you do the Elite 4 will appear and are the leaders of each island.
New Pokémon design include a dolphin, sea cucumber, snowman, mushroom and a rugby monkey.
Mashadow as a very unique type combo
And apperantly the leak starter image has disappered from google search terms.
