Soul Calibur will arrive on the iOS App Store on January 19, and it looks mint. The iOS version is a port of the Dreamcast game with all 19 characters present and correct.It also includes a nice selection of modes: Arcade Battle, Time Attack, Survival, Extra Survival, Practice and Museum modes, and support for Game Center Leaderboards.
There's no word on price, but who cares? It'll probably be cheap and as Street Fighter IV showed, fighters work surprisingly well on the touch screen (if you don't take things too seriously).
