Well, think about it. In all the other seasons/regions all the legendaries have been featured somehow, either in a movie or in an episode, or a special. But Sinnoh has 14 legendaries, so how would all of them be featured?
We know Dialga, Palkia, and Darkrai are in a movie, and Manaphy has already had a movie. It's probably a good bet that Phione won't have it's own movie, and if it appears at all it'll be in an episode. That still leaves Uxie, Azelf, Mesprit, Heatran, Regigigas, Giratina, Cresselia, Shaymin, and Arceus. Your thoughts on which ones will get movies?
