It looks like Soul Calibur 4 (Xbox 360, PlayStation 3) is another game you won't be able to try before you buy. Namco Bandai recently made it known that they won't be releasing a demo for Soul Calibur 4 until after the game comes out.
Joystiq reports that, according to some company representative manning the E3 room, the developers are putting their focus on getting the game out in time for the scheduled release date of July 29.
Fans of the genre will definitely be picking up this game, with or without the demo. As for everyone else who's still on the fence, sit tight. We'll report back with more info on a demo for the game as it becomes available.
