This was written YESTERDAY in pokexperto, by an anonymous user called Kato, I post this here because he talked about the buffalo and the CoroCoro stuff was not revealed yet, so take it as you wish (could be fake):
"Hiro, Melkor, I am the sacred cow. Let me do this, is a gift that I do to myself. Today was a special day. Do not worry or be angry. Thank you. Continue being the same.
In this generation there are 3 trios. The typical four-legged beasts that are inspired by the three musketeers.
Steel/Fighting equivalent to Athos, courage pokemon, is blue with yellow horns
Rock/Fighting equivalent to Porthos, corpulence pokemon, is gray and very sturdy, like a bull.
Grass/Fighting equivalent to Aramis, elegance pokemon, is green and stylized. His shiny version is completely pink.
This trio complements with the Water/Fighting pokemon, is a pony with an orange mane, like the feather of the hat of D'Artagnan. This is an event pokemon.
The event pokemon that have 2 forms, the female form is the constant melody pokémon, equivalent to Constance, D'Artagnan`s girlfriend. The basic form is Normal/Psychic and the alternate form is Normal/Fighting. The first form have loose green hair and the second form have the orange color hair tied up like turban. In both cases, her dress is black.
Then we have the Raijin trio, genies sitting in clouds. The pure Flying type is green. The Electric/Flying is blue and the Ground/Flying is reddish brown a white hammer behind his head.
The final trio are the dragons Reshiram, Zekrom and the "frozen chicken" that nobody is going to like, is the ugliest of the three dragons, Dragon/Ice. It is curious that the second type of the dragons is directly related to the type of the legendary birds .
Shiny Reshiram have pink tones.
After the 3 headed hydra there are 2 Bug/Fire pokemon.
Also, there are a Tauros with afro hair, 2 dark type vultures, 2 psychic type aliens.
A fire type anteater and a Bug/Steel ant.
New combinations are Ground/Ghost, Ground/Electric that is a sole, Water/Ghost that are a prince jellyfish and a king jellyfish, and Fire/Ghost that is a candle which becomes a lantern and finally a spider-shaped candelabrum.
PS: Boys, the rest is all yours. Congratulations."
