I found this on newsarama while searching for Batman and Wonderwoman (due to the Bruce belongs with Diana forum.) So I hope you like it there is also a concept art that is not very clear but alrighth in my opinion.
There is also a Wonderwoman movie about which I posted at her page.

Rating: PG-13 (anticipated)
2-4 weeks in advance of The Dark Knight film release.
Set in the period between BATMAN BEGINS and THE DARK KNIGHT, this brand new adventure follows BATMAN as he unravels a mystery over six original stories done in the style of Japanese Anime. Each of the six original stories has been written by a highly respected screenwriter or comic book creator. The talent includes Academy Award nominee Josh Olsen (The History of Violence), screenwriter of the Blade films and Batman Begins David Goyer, and famed comic book writer Brian Azzarello, among others.
The Batman Anime DVD is viewed as a perfect companion piece to BATMAN BEGINS and THE DARK KNIGHT. The original stories introduce a number of classic characters from the DC Comics BATMAN universe as well as following up on characters and storylines that were introduced in BATMAN BEGINS.
When asked about the two projects by Newsarama, Warner Bros. Animation declined to comment.
