In 4-6 years, when GF remakes Kalos, they SHOULD do a definitive edition Pokémon-Z. Make a few new gyms to replace disappointing leaders like Wulfric, increase the number of Pokémon each gym leader has and give them good items, add a worthwhile battle frontier area, throw in a permanent mythical story (like deoxys in ORAS, but a Gen VI mythical), make both box legendaries catchable, correct the story, and write a cool story for Zygarde complete.
But instead we’ll get “faithful” x/y remakes, except with mega evolution potentially removed.
