A thing was said on THQ's page about it. "Our Make-Good DLC is not Chris Jericho."
And then later said "Our make-good DLC doesn't just "break the walls down", but destroys any wall put in front of him with his monstrous power"
Yeah, it could be Kane.
But for some reason, I think it's going to be a reused version of Andre The Giant from a previous game.
Well, we know it'll be a big man, whoever it is, from that description.
