Yeah. Gon has met his goal and doesn't particularly have any shounen quest in mind at this point. Moreover, Ging's dream sounds like something that will need twice as many episodes as what we have had so far, so even if Gon decided to follow the same path, the mangaka would never finish it in our lifetime, with his working speed, or rather a lack of speed. Thus, this is a good point to end the show. I doubt we will see a continuation anymore. This was purposefully a fillerless version of the story, so it's not like they had a choice in any case.

Not a bad last episode, all in all, even if so uneventful that Ging telling the chicks to shut up was the highlight...
