Hmm seems that Nintendo is cracking down hard on the people who got the game early. Tried looking up the early release screenshots, but I saw nothing on Fennekin's final evolved form. Well I saw an image that was supposed to have artwork for it that was supposedly leaked, but the consensus on the comments seemed to indicate that it was a fake.
I have to say though that PokÃ©mon X seems to be getting the better looking Mega evolutions. That is really tempting me to get X over Y, but I always go for the "red" version. Decisions decisions.
