Despite your choice of abbreviation being different from mine, I will ignore it and accept that people have their differences and that no word is inherently the "correct" word for referring to a thing, when another word is equally understood.
That said, I do not think it is very likely we go back to Kanto or Johto. Surely 24 Gyms and 2 Elite Fours are too much for the average player, no?
