Looks like a couple of Catwoman moves I hadn't noticed before popped up in that trailer. I didn't know she had the Hurricanranna and the whip slam, but then again I've been pretty busy with finals.
I can't wait for this game. I'm hoping desperately for The Ray to make it in as one of the promised insane niche choices. He likely won't, but my love for Raymond Terril is pretty deep considering he was in the first DC comic I owned which was a Justice League of America "Destiny's Hand" comic (the one with Hawkeye on the cover in a yellow lantern ring).
Guy was pure swag and had he not comeout with a flurry of others like Superboy he likely would have taken off more. I could go on forever, but it basically boils down to nostalgia and pure visual appeal with his look that make me love the guy. Its like he had every energy effect all at once.
More realistically though I am also hoping for Green Arrow. If he makes it in I will cosplay him for Injustice-GAF just like I did for Deadpool for Mahvel-Gaf. Gonna shoot me some arrows
