The real reveal in the trailer is that Kevin Conroy is back to voicing the Dark Knight once again after his last stint in Batman: Arkham City. Conroy has been the voice of The Goddamn Batman longer than any other actor in live-action or animation since he first took the role in Batman: The Animated Series in 1992. Though the cast has not been revealed, any die-hard Batman fan will recognize the voice instantly.
Rumors say that the plot follows a clash between Batman and Superman, with this statement by Blur Studios:
An all-out battle rages between the forces of Superman and those allied with Batman’s rebellion. Time has stopped—the world completely frozen in a instant of time—a moment where violence has boiled over and could consume the meta-human community
Blur Studios was responsible for the first Injustice trailer. Injustice: Gods Among Us comes from Mortal Kombat creators NetherRealm Studios who plan a more over the top fighting game for their latest title versus the more bloody work they are known for.
Injustice: Gods Among Us is due out sometime in 2013 for the PS3, Xbox 360 and Wii U.
