I am really interested in what Araki will bring to the table in JoJolands, since there is always some kind of distinct theme for each part. Considering Araki has wanted to do something in Ireland or around its islands (and the working title is JoJolands), I wouldn't put it past him if he were to create a sort of sea-themed adventure where the main cast are sailing and exploring the world. I would be fascinated in seeing different cultures explored within part 9 and having another sort of around-the-world adventure within the part like part 3. I am also curious in seeing if King Crimson and or Whitesnake will be included into the part, but we'll have to wait and see!
I think regardless of who we have, I want someone who's got a unique personality or character traits. I'm not saying that any of the other jojo's felt bland or too similar (they're all unique in their own way, which is part of the fun for me) but I've been really impressed and have enjoyed the uniqueness of Johnny and Josuke/Gappy. I feel like AU jojo's have been really fun to watch and get to know, so I look forward to seeing what Araki does to continue that trend. People often cite the creativity of stands or the musical references as some of the best parts of Jojo, but I would add that Araki's ability to create fascinating characters is where he often shines and is overlooked. Can't wait to meet our next jojo!
