1. 20th anniversary is coming up
2. Kanto is the one region that could use an overhaul
I'm still not convinced the next two games are going to be XY2. There could just be a Z version where Zygarde learns both Thousand Arrows and Waves leveling up. In that case, I could see them going the Rayquaza route and not requiring a mega stone to evolve. But at any rate, that leaves one game with the Gen 6 pentagon possible, and you know a Kanto remake would sell a sihtload of copies just for featuring the original region.
