We did learn about the devil fruits, they came from people's desires.

@FolhaS
I’m not sure I understand the process in which desires turn into fruits. When and why did it happen? The answer for that would be, for me, an explanation. What we got was more of a hint. -
@Chams-0 Yeah, that's true.
To be honest, I was expecting a bit more lore/info about the fruits from Vegapunk before the arc, specially since VP can manufacture them, but technically Oda did deliver on the promisse that we'd learn where devil fruits come from, they come from people's desires.
I'm guessing/hoping we'll see more of the process when we get to a Ancient Kingdom flashback and that Oda prefers to show it then rather than just tell it now.
