So people have already been guessing Froakie may be dual fighting by its second stage, Fennekin may be psychic, and Chespin may be Dark based on moves seen in the trailer and what have you. Could we finally be seeing the incorporation of a secondary starter triangle? People have talked about it for years, and because Psychic can't hurt Dark and it wouldn't work as starters' primary type triangle, it would work for the secondary type. Give starters less of an advantage by the final stage with the reverse triangle.
If Froakie does turn out fighting, I don't quite get what GF's thing is for Water/Fighting frogs.
