Like chespin, froakie is kind of a mystery too. You can't really predict what he'll look like when he evolves. A lot of people seem to like fennekin, but I personally think froakie is going to turn out to be something really cool.
I'm excited because I enjoyed the fifth generation so much, and I'm looking forward to seeing how this generation does in comparison. And I also love the excitement of having new pokémon revealed.
While I did miss the reveals (come on who doesn't like those, it's like Who's That Pokemon all over again) I'm not thrilled about having to get the 3DS... the legionaries don't look that promising either.
