As you can see it's a pretty radical design. Almost like they crossed Batman with Shredder. Still it is very cool, and would look awesome on the mantle of my fireplace. Currently its working title is simply "Batman (Designed by Tetsuya Nomura)." If you are going to SDCC you can see the prototype figure at the Square Enix Booth #3829.
