On Sunday September 29, two anonymous users posted convincing images of Game play from Pokemon X and Pokemon Y. Early in that morning, a poster leaked three images of the final evolution of Frokie, Greninga, and he or she also revealed the new Flying Fighting Pokemon Hawlucha, which has learned a new fighting move Flying Press, which has a PP of ten. The other user, while not reveling much, did show us a new Rock and fighting Pokemon called Binacle. While these could be faked, I believe, along with about 1000 others, that these are legit. How these two obtained X and Y, while not being trust worthy enough to keep it a secret, remains unknown.
You can see the five images below:
