well folks, based on what we know so far from the future mini-series titles ( 6, 7, 8, 9) and previous episodes that have aired, I assume the point of this mini-series is to tell the fans what will become of Ash after achieving his goal of being a pokemon master. He'll just simply travel the world, meet new pokemon, and possibly compete in more tournaments. Which is basically nothing new from what we seen him do from the original series.
Other than that, so far i'm fairly disappointed with how this mini-arc is wrapping up. Honestly, I did expected some episodes to be laid back, but I didn't think it would overtake nearly most of the mini-adventure. Looks like pallet town will be the final stop to this adventure where Ash meets with Oak, and then Gary to reminisce on his most recent adventure, in which Gary pops the question about Ash's goal; Pokemon Master.
However, I do expect Professor Oak to pop the question about Paldea, which excites Ash to go on another adventure to the new region, giving us the anticipation to see him in the new 2023 anime story, thus luring older fans to watch it.
Other than that, this does not feel like a story arc finale. Look forward to seeing Ash in the new series.
