Anyways, the 11th movie site was recently updated and in the updates was an official confirmation of Shaymin in the movie and a new form of Giratina!?!?! Magazine scans foreshadowed that Giratina
I took a screen cap of the new images from the site for your viewing pleasure.
You may also visit Pokebeach for scans from CoroCoro magazine.
