After watching the Gamescom and PAX gameplay footage, I have compiled a list of all the moves in Eryx's moveset. I don't think a movelist was compiled for it yet, so I just thought I ought to. I'm not really sure about the names, so correct me on them if I'm wrong. I'm using PS3 controls for button commands.
Brawler- A heavy three- punch combo: Triangle, Triangle, Triangle
Slam- A two- hit combo followed by a punch to the ground to create a shockwave: Triangle, Triangle---> Triangle
Showdown- Pound your enemy back onto the ground: Triangle (while in the air)
Snake Eyes- A quick feint- step followed by a heavy punch: Up, Up, Triangle
Uppercut- self- explanatory: Circle
Stomp- Slam into the ground to create a shockwave: Circle (while in the air)
