Pokémon Movie News
Japanese variety show, Oha Suta, has shown the first details of the brand new movie. This movie, titled Kyurem VS The Sacred Swordsmen (キュレムVS聖剣士), and is set to feature the legendary Pokémon; Cobalion, Terrakion, Vizirion and Kyurem. This movie is due for release in July 2012 in Japanese theatres. More information of this movie will come on the official site on December 17th. Our friends at Filb will have the trailer shown in high quality shortly. In the meantime, pictures have been added to our pre-release page
This was reported on Serebii and assuming that Kyurem is the mascot for the third game this may have some connection to the game being Pokémon Grey. This is by far no confirmation but it could be something.
