So, I don't have an exact idea of WHO is gonna be the villain, but I have some confidence of what their stand ability most likely will be
In Pre-Reset JoJo had a pattern with its Villains Stands
The World: base ability time related
Killer Queen: time related ability attained
King Crimson: base ability time related
Made In Heaven: time related ability attained
Its a pattern, now look at Post-reset JoJo
D4C: luck related ability attained
WoU: base ability luck related
So, if Araki is sticking to the pattern, the next villains stand is most likely going to have its own unique ability an later on attained a luck/misfortune related one near the end.
I'd like to see if you agree or disagree and why
