No, we will never find out who Ash's dad is.
We will never see Ash accomplish his goal and come back home, running into his loving mother's arms, to grow up happily with her and Mr. Mime.
We will never see Jessie, James, and Meowth get to be happy.
We will never get to see them visiting Ash to reminisce about trying to steal Pikachu, only for it to turn into one last half-joking attempt at it.
We will never see Brock or Misty go back to their gyms. We will never get to see the main characters get to be normal kids and dudes. They will never go to school or graduate, they only live to be thrown away.
We will never see how proud Oak could have been when Ash comes back with league wins, ready to study, and we will never see Ash become a pokemon professor just like him.
And we will never see Ash finally reunite with and marry the love of his life, Latias.
