Update by Ahmed Mosly: new teaser is up. Check it out!
We have virtually nothing to go on right now other than to confirm Soul Calibur V is officially coming to the PS3 and Xbox 360 sometime next year. The game’s fictional story takes place 17 years after the previous entry in the series and we can confirm that both Siegfried and Nightmare are featured in the game. More info as it breaks including a teaser trailer.
