From the PlanetXbox360.com feature top list:
"Is it too early to start talking about Injustice? Of course not. For those of you unfamiliar, NetherRealm’s second attempt at a DC fighting game (slated for a tentative 2013 release) promises epic battles on top of epic battles. Injustice: Gods Among Us is proving to be a unique look into the superhero world with exclusive characters from the DC Universe. The game already boasts some it’s over the top action with its incredible interactive environments and an already promising list of playable characters. So far, the announced characters include Superman, Flash, Batman, Solomon Grundy, Wonder Woman, Harley Quinn, Nightwing, Cyborg, and Beast Boy. But what about the rest? With so few characters announced, there seems to be plenty of space left that will complete a (hopefully) much larger cast. Without further adieu, I attempt to shed some light on DC’s colossal fighting game with an early look into a possible playable characters roster."
