Sun and Moon leaked early to a few people, and the games have been cracked open and datamined completely, so we now know the typing, stats, abilities and movesets of every new Pokemon, as well as version exclusives.

On top of those already announced by the Pokemon Company, Alolan Vulpix/Ninetails and Turtonator appear to be exclusive to Sun, and Alolan Sandshrew/Sandslash and Drampa appear to be exclusive to Moon.
