Mark my words, the 18th Pokemon movie will not be Xerneas vs Yveltal vs Zygarde, it will be Zygarde vs Volcanion. It all fits:

>a secret legend is always included in the second film of the generation
>the next secret legend by dex number is Volcanion
>clean energy, power plants and the environment (global warming) are relevant topics at the moment
>Zygarde's environment aspect has nothing to do with Xerneas and Yveltal. On the other hand environmental issues and power plants go hand in hand.

The december Oh Suta trailer will be Zygarde destroying shit. Then we'll find out Volcanion is in the film too (in Feb when they announce it in CoroCoro). Volcanion will be polluting Zygarde's terrritory, they'll fight each other, probably both get new forms, and live in harmony at the end.

then the 19th film will be hoopah and mega lati@s, just in time for the RSE remakes
