Keldeo AND Meloetta to be distributed with the 15th Movie

quote PokéBeach

The official Pokemon movie website has revealed that Keldeo will be distributed to players who pre-order a ticket to Kyurem vs. the Sacred Swordsman - Keldeo while Meloetta will be available for download at the actual movie theaters. Thus, this will be the first time two "hidden" Legendary Pokemon are promoted at the same time. Genesect will likely be revealed next year for the 16th movie.
The fact Meloetta is being revealed this early lends credence to the fan theory that Generation V will end sooner than expected and that Generation VI will debut within the next two years on the 3DS. There are several possibilities here: if we're getting Ruby and Sapphire remakes this generation, they will likely be promoted next summer (maybe we'll get Kyogre and Groudon with Genesect or the Regi's with Genesect). Or, we could jump straight into Generation VI, then have Ruby and Sapphire remakes sometime during that generation. Or, we might not get them at all - who knows. At this point, it's too early to predict what's going on, but what does seem to be for sure is that this generation is being sped up.
The movie website also revealed new anime artwork for Meloetta, as you can see below. There are still no signs of its Ken Sugimori artwork or its Normal / Fighting "Pirouette" Forme - maybe the forme is meant to be a total surprise for those who download it to their games in July?

Update #3 (Thursday) - Due to a huge mistranslation on our part, we erroneously reported that Meloetta will be downloadable at movie theaters. That news story has since been deleted - we do not know yet what Pokemon will be given out at the movie screenings. We apologize for the misinformation.
