I actually hoped Gen 5 would be last. Oh, Satoshi.... How I miss your work. But, hey, six is the max party members at one time so, it's a good number. I'll let it slide.
I noticed a decline in the designs in Gen 4. I even hated a large amount of Gen 5 designs..... Now, I think they just went off the deep end. Gen 1-3 was really good though. For those who don't know, Satoshi Tajiri (The Single Creator of Pokemon) stopped helping with the designs after Gen 3... Notice a pattern?
Anyway, personally, I don't like any of these. Although, if I had to choose, I would go with Fennekin.
Anyway, Time for typing speculaton.
Chespin looks like it might spawn a Grass/Ground. It's color scheme and feet look like a give away.
Fennekin, I'm uncertain. Though, looking at that smug expression on it's face combined wih the fact that it is a fox, I'd say a Fire/Ghost
Froakie is also uncertain.It's color scheme looks like a flying type but, a Water/Psychic type looks better. Psychic is the closest we have to magic and that cape,mustache and gloves almost scream 'wizard'.
Well, at least these actually look like pokemon... Unlike the legends but, this isn't the thread for that.
