Red Mile has signed the license to Frank Miller's Sin City graphic novels and comic books; signed Flint Dille, known for The Chronicles of Riddick, as designer/scriptwriting; and revealed Sin City: The Game will be powered by Epic's Unreal Engine 3. Sin City, currently scheduled for Christmas 2009, is being developed by Transmission Games, formerly known as IR Gurus, and since the Wii is one of the platforms, could they be the mystery developer porting the UE3?
