EDIT: There are some new Pokémon:

Its name is Emonga (エモンガ). The Flying Squirrel Pokémon, it weights 5kg and is 0.4m tall. It's an Electric/Flying-type and its ability is Stactic. Does it not look too much like Pachirisu?

Gigaiasu (ギガイアス), an already known Pokémon. The High Pressure Pokémon, it weights 270kg(Wow!) and is 1.7m tall. It's a Rock-type and has Sturdy as its ability.
Darumakka (ダルマッカ). It's a Fire-type and could be the pre-evolution of Hihidaruma.
There's another Pokémon with no picture called Basurao (バスラオ),which knows the moves Aqua Jet and Uproar.
Finally, the move Growth won't only raise Special Attack, but Attack too by one stage!
When Coro-coro magazine come out, there will be many news like these ones! What's your opinion about it?
