lol, I'm glad somebody for once points out the inarticulation and seeming illiteracy of some of the posters on here. I guess it's excusable if you're 11 or if English isn't your first language, but otherwise some of you seriously need to work on your communication skills.
Oh, minor, but wanted to add: the next Soulcalibur needs a quality opening that features the entire cast. SC3's was the perfect mix of evocative and exciting. SCV's on the other hand has been compared to an episode of Dragonball Z, and I don't doubt that's far off.
Rebalancing, new moves, Critical Edge select
