My favorite is the Dark/Ground Crocodile, but I've been a fan of Zoroark since seeing him too.
Anyway, I don't find it likely that the Chincilla will be this gen's Bidoof. It's a psychic type, and the vendor trash pokemon is always a normal type. It's tradition.
Hihidaruma---is based on the Daruma statue: https://en.wikipedia.org/wiki/Daruma_doll Its name means "flame flame daruma."
Zoroa and Zorouk are nice looking but their already becoming overrated to me, much like Lucario was and is since its movie, not to mention Riolu D:<
I really can't wait for this gen @_@
