From the preview: "The announcement that Vader would be a exclusive playable character for the PS3 version of the game, whilst Yoda would fulfil the same role on the Xbox 360, instantly sparked owners of each console into arguments with the kind of cut and thrust normally reserved for the game's one-on-one bouts.
Soulcalibur's premier on next gen consoles also marks the introduction of online play to the series and this is even more appealing given that you will be able to take your own created characters into these tussles, thanks to the return of the options first introduced in Soulcalibur III. As well as online play, Soulcalibur IV will also feature the standard Arcade and Story mode, as well as the new Tower of Lost Souls option, which brings further customisation choices and rewards into play."
