Serebii has finally begun their X and Y coverage, so now I've been able to see what new Pokémon there are. Hmm, only 69 new Pokémon? Hmm... I would've expected more. I'm kind of glad Sylveon's the only new evolved form (not counting Mega Evolutions, obviously) of any old Pokémon.
Still going with Fennekin in X and Froakie in Y, even if Greninja's tongue looks kind of weird, and is making me reconsider whether RP!DS should get a Froakie or not. (I do have a bit of a funny idea for it if I do have her get one, though)
Not sure what other Pokémon I will use in these games, though, nor what else to have RP!DS get, other than her Furfrou and Inkay/Malamar. (and possibly the Froakie mentioned above)
I am sort of toying with having RP!DS get a Flabébé, but I also have an aspiring Fairy Specialist character in mind, so maybe... I don't know...
