The character's depiction in the New 52 has been mostly along the same lines as the remainder of her modern appearances, though as of yet much remains to be explained about her character. One development with the character in this new universe is that some of the developments which occurred during Flashpoint are occasionally referenced (such as her using London as her base of operations). In her New 52, written by Brian Azzarello, Wonder Woman's origin is that she is the daughter of Hippolyta and Zeus; no longer is she a golem of clay and earth, but an actual demigoddess.
Steve Trevor died at the end of Wonder Woman after sacrificing himself to ensure that a plane full of deadly gas couldn’t harm anyone on the ground. Is this Steve Trevor the same Steve Trevor that we saw in Wonder Woman who was transported to 1984 because of something like time travel, a descendant of Steve Trevor’s who is also named Steve Trevor (and looks exactly like Pine), a clone, or something else entirely? (It’s a comic book movie, so anything is possible.)
The I Ching era had an influence on the 1974 Wonder Woman TV movie featuring Cathy Lee Crosby, in which Wonder Woman was portrayed as a non-superpowered globe-trotting super-spy who wore an amalgam of the Wonder Woman and Diana Prince costumes. The first two issues of Allan Heinberg's run (Wonder Woman vol. 3, #1–2) include direct references to I Ching, and feature Diana wearing an outfit similar to that which she wore during the I Ching era.
When Diana returns she takes on the persona of Diana Prince, now a secret agent and member of the Department of Metahuman Affairs. She is partnered with Nemesis and the two report to Sarge Steel. Her first assignment is to retrieve her sister Donna Troy, who has been kidnapped by several of her most persistent enemies; their powers have been augmented by Circe. After this is accomplished, Diana takes back the title of Wonder Woman.
The Diana Prince alias also played an important role after the events of Infinite Crisis. Wonder Woman was broadcast worldwide killing a villain named Maxwell Lord, as he was mind controlling Superman into killing Batman. When Wonder Woman caught him in her lasso, demanding to know how to stop Superman, Maxwell revealed that the only way to stop him was to kill Lord, so as a last resort Diana snapped his neck. To recover from the trauma of killing another person, the Amazon went into a self-imposed exile for one year. On her return to public life, Diana realized that her life as a full-time celebrity superhero and ambassador had kept her removed from humanity. Because of this she assumed the persona of Diana Prince and became an agent at the Department of Metahuman Affairs. During a later battle with the witch Circe, a spell was placed on Diana leaving her powerless when not in the guise of Wonder Woman.
