While the chances of us getting platform-specific characters, like Spawn, aren't very likely in Soul Calibur IV, Namco is hard at work at offering other bonuses. In an interview with 1up, Katsutoshi Sasaki, the game's director, said his team at Project Soul is looking into the possibility of including Sixaxis motion control. He said it's "something that we're considering, but we'll have to come up with some good ideas for it first."
But that's not all. In the same interview, lead programmer Masaaki Hoshino said they're also hoping to give gamers the ability to save their custom characters to the PS3's memory card and take it to a friend's house to do battle.
Although it seems like it would be difficult for the developers to include any sort of motion control that would make sense, toting your custom characters on a memory card would be pretty handy. All we care about, though, are Ivy's friends and finally some Soul Calibur online action!
