The Soul Calibur film rights were picked up several months ago by a private company named Second Degree Media. The title of the project is currently entitled "Soul Calibur: Endgame". One thing to note about the storyline is that it involves the Soul Edge (as a shape-shifting weapon) being the driving force behind next to every warrior/shogun/conquistador who have come to rule over a land and whose names have stood out throughout history.
Warren Zide is not involved in the project as of right now, nor is any studio as of yet. A late 2007 release can be expected.
