The most recent runs refers to Diana being born of clay, Worlds Finest also refers to her as being born from clay and even Historia (which is not canon but is considered to be by many fans) also refers to the clay origin.
I suspect WW's origin is going to depend on what they do with her in adaptations. So we better pray that Gunn uses the clay origin in Paradise Lost.
