I hope this means Team Rocket may be the main villain team once again. I would love to see their story develop a lot more, especially the mysterious Giovanni and what he's been up to. Possibly creating this new version of Mewtwo and the story is revolved around that. In my opinion, the box legendaries shouldn't be involved with the story at all. They should be kept mysterious and away from the generic story line of Pokemon ( the main villain team wanting to use their power somehow) and instead be something the Trainer has to find out by searching for clues and stories from various people in different cities and towns. I'm just speculating some unique ideas Gamefreak could pull.
