OK, I don't have an official confirmation, but I think I found the "script" for the rest of this season. Basically, what we can expect in the remaining episodes:
1º) Between April and May: One more mission for the Ultra Guardians, involving the still not debuting Ultra Beast, Kartana.
2º) Possibly in June: Showdown against Team Rocket, probably involving the plot in the games about "Team Rainbow Rocket" and getting control of the Ultra Portals and Ultra Beasts. This could have some extra consequences, like the improbable but not impossible return of Ash's Poipole. Also, we could have the return of Guzzlord and atacking Ash's reality. This could also bring us the return of Dia.
3º) July and August: All the episodes will be about Alola's Pokemon League, just like when the Leagues of Sinnoh and Kalos took place (and I mean they were originally aired in Japan).
4º) September: Final episodes of the season and the Generation. Ash graduates at Pokemon School, says goodbye to his friends and returns to Kanto. Just like when in real world, summer ends and kids have to go back to school. Next Generation at the anime either starts at one of the last episodes of September (probably), or in October (unlikely).
Well, what do you think?
