Kanto / Johto: Indigo Plateau Hoenn: Ever Grande City Sinnoh: North of Route 223; "Pokemon League" on map.
The elite 4 are in the north-east corner of the sinnoh region
I have the strong feelin that Ash will win this one because in the flow of pokemon history Ash becomes closer and closer to become a champion and in the sinnoh league, he is in the top 4 and i think in unova, in the finals Ash will battle Trip and Ash will win against him and become the winner and after that he will proceed in battling the elite 4 in different kinds of regions and enter the "Champions League" where champions in different regions battle in order to win and face the Pokemon Master and Ash will battle the Pokemon Master and then claim the title....
