Pictures of the CoroCoro magazine have leaked early as usual and this month’s issue reveales Keldeo! Keldeo is shown as the 153rd Pokémon in the Unova Pokédex and the magazine also confirms that Keldeo will be the star of the next Pokémon movie as its title is now changed to “Kyurem VS The Sacred Swordsman – Keldeo” [キュレムVS聖剣士 ケルディオ]. Nothing more is known for the time being, if any new information surfaces, we will update this post.
On a side note, the Mewtwo Wi-Fi distribution for English language B/W games is currently running, get it while you can!
