OK although I like the Froakie design, here's what Im seeing:
Lets start with Fennekin, seeing as this is the easiest. first of all Braixen is not a psychic or fairy type, just plane fire. There is Nothing on this evo that even implies those two besides THE STICK. the stick becomes magical, grows longer and bendier by pure chance, and suddenly, psychic and/or fairy! Not to mention the only thing that led us to believe this in the first place was the supposed dormant minds eye on fennekin's and braixen's forehead, which is missing on the new evo. either this new evo is too cool for weirdly prominent fur features, or its not psychic at all
Furthermore, if we looks at all the small details they are rather similar between Fennekin and Braixens design. Ear tufts have two tips and and two smaller ones near the ear and are both red, this evo has 3 tips and only one small one near the ear, and they have suddenly turned white and added blue to make purple.
both Fennakin and Braixen have pure yellow ears, this evo migrates its ear tufts to the top of its ears.
Both Fennekin and Braixen have sideburn like tufts split down the middle on the side of their face, this evo only has one big tuft which is odd because the ears just told us "more tufts=better"
The same goes for Braixens collar which appears to have changed from combed fur into a white plastic bottle blown up from the bottom, with sharp out-sticking spikes
First Braixen changed arm colors now this new evo went and changed them again, that's a weird part of the body to constantly change color then revert back to the original color with a black accent to it.
Its "Skirt" has completely extended in a way that looks like the skin of a smashed onion, once again losing its fur like quality.
Too me Fennekin's supposed evo is a case of trying too hard, needs to look like Braixen yet it needs to be different in everyway without making much sense.
As for Froakie's Evo, its more believable, because one, it grows its bubble hood like anyone would, despite there being a tail now, something frogs get rid of when they grow not get more of.
It is also obviously based off a dart frog, but that's the original rumor said, but this image isn't from the leaker of the original rumor so its not like some guy could see that and make this to seem real.
The weirdest feature by far however is how as a frog based on a real life frog with no claws, grows them out of nowhere, and furthermore grows ones of different colors for his hands and feet.
not to mention, how many animals with claws do you know specialize in doing extreme jumps? i'm not talking about death pounces, I'm talking about jumping high in the air repediately in order to travel. Claws are for running cutters, not bouncing kickers
As I mentioned earlier he has the obvious speck on his knee, which really is just un-professional in that it was either accidentally left there or the creator thought it would pass off as light glare when the only other area this is apparent is his shoulder whilst the rest of his body has no sheen to it at all.
Lastly his nose bubbles have become prickly when in the first place they were supposed to represent the familiar nose holes on a frog face, but now it looks like has has no nose but an eccentric mustache.
Yes he is cool looking and I wouldn't complain if he were real, but their are a lot of oddities that can't be ignored
IN SHORT, trickery is afoot.
