Looks pretty cool so far, and I don't have too much more to offer, other than some trivia regarding the new starters:
Chespin: I'm not really sure what Chespin is supposed to be, exactly, but it definitely looks like a mammal, as opposed to Bulbasaur, Treeko, Turtwig, and Snivy, all of which are based off reptiles (I'm not really sure what Chikorita is supposed to be, but since Meganium looks like a brontosaurus...), thereby making it the first grass-type starter not based off a reptile.
Froakie: Also on the subject of animal classes, the water-type starters so far have been reptiles (Squirtle and Totodile), a fish (Mudkip), a bird (Piplup), a mammal (Oshawott), and now an amphibian, meaning water-type starters have the most diverse set of animal classes.
Fennekin: The most evolved forms of the fire-type starters have been a dragon (Charizard), a rat (kinda) (Typhlosion), a rooster (Blaziken), a monkey (Infernape), and a pig (Emboar). Since Fennekin is a fox (and assuming its most evolved form is still a fox), this makes it the first fire-type starter not to be based off an animal from the Chinese Zodiac.
Anyways, it's just some random stuff I noticed. When it comes out, I'll probably go with Fennekin because it's a fox and foxes are cool (though frogs are cool too, so I'm totally cool with Froakie).
