Do you see pokemon continuing in making new regions or will Game Freak take a break and add some variety to their usual such as past history of the older regions or the future.

Well, my standard answer to this kind of question is that I expect Game Freak to continue doing what’s been proven to work in the past unless they explicitly tell us otherwise.  Things like the basic format of the game are part of their tried-and-tested recipe for success, and although I might like them to do something different, I kinda doubt they will.
