The first details of CoroCoro appears to have come out. With special thanks to my friend Gin for translation. First, the Pokémon on the far right is called Gogoat (ゴーゴート literally Gohgohto) and is the Riding Pokémon. It's Grass-type, 1.7m and 91.0kg. You can actually ride this Pokémon in the field. It can learn Horn Leech
The lizard is called Elikiteru (エリキテル) and is a Electric/Normal-type. It is the Generation Pokémon and is 0.5m and 6.0kg. It has a new move called Parabola Charge which heals the user while damaging opponents. It uses solar rays to generate electricity
The bird is called Yayakoma (ヤヤコマ) and is the Japanese Robin Pokémon. It is Normal/Flying, 0.3m and 1.7kg. It announces itself with a beautiful voice. It can use the move Flame Charge
The panda is called Yancham ( ヤンチャム) and is the Naughty Pokémon. It is Fighting-type, 0.6m and 8.0kg. It has a new move called Parting Remark
There appears to be more including the game's boxarts, and the Pokédex, as well as the region map but it's not completely visible. We'll bring more as it comes so be sure to keep checking. It also promises more information on Gogoat on a later page.
Edit: The game is set in the Karos Region which appears to be based on France. You can customise your trainer slightly with hair colour and skin shade. Main city is Miare City which is where it is seen to ride Gogoat
Edit @ 15:22: We have the cover and it shows that these four Pokémon may be the only new ones in it. It also shows the boxart
Edit @ 15:48: Closeup image of the customisation
