my dad is a writer for the tv show and he said:
>ash wins the league and goes on to train at the Battle Chateau
>Ash beats Diantha in the final round of his Chateau
>then he gets invited to the Champion League (filler arc between games)
>all of his old rivals are there including Paul, Ritchie and Gary (who won the Kanto League)
He then told me that Ash and Misty reunite and get married and Serena falls off a cliff somewhere in Johto, then their kid is the new hero.
