I was doodling Chespin and Froakie earlier to help myself get used to the designs, and I gotta say, the more I look at Chespin, the more it makes me think it'll be a dark type. There's just something that fits when you draw it with a sneaky little smirk... And that little hood! It doesn't look like a helmet to me, like some people have said, though its arms do look like they'd be great for punching.
