We've not seen Diana's origin story in the 52'Verse yet. They've introduced her as established already...and we've seen an earlier more naive version of the character in the opening arc of Justice League. All we know about her in the present time of the real world is that she's involved with Steve Trevor.
I like what Azzarello has done with the Greek Pantheon personally. I thought Ruka's run was decent, but Azzarello has made things interesting IMO.
