The guy claims to have the game already.

Looks legit. He's answering questions on his Youtube channel

There's more people out there with a copy of the game. I saw a live stream with Arturo Sanchez on his Twitch Channel, where he was playing guys online. There's people out there who're already level 51+.

Got to see a few cool moves, though most of the gameplay was just Black Adam divekicks and lightning bolt spams. -_-

Got to see a pretty decent Yellow Lantern player, some insane Nightwing combo's and Hawkgirl's trait (flying).

Not sure if he's going to stream today, but this is his channel: http://nl.twitch.tv/nycfurby

I like this combo video better.
