Injustice: Gods Among Us character roster, which shouldn't be a terrible surprise to anyone. The announcement was made through a series of tweets by NetherRealm creative director/founder Ed Boon.
We can't wait for a few months from now, when Boon and crew have burned through all the obvious character choices and start announcing some weird deep cuts. "They announced B'wana Beast for Injustice," someone might say near/around a water cooler one morning. "Yeah, I don't know either."
Update: As promised, the above screenshot was indeed delivered before the end of the day. A high-resolution version awaits your scrutinizing inspection here.
