While Soul Calibur isn't my favorite fighting game series by a long shot (I prefer the simplicity of Super Smash Bros. and the insanity of Guilty Gear), I do like it enough that I will probably get SCIV sometime in the future. I don't have a PS3 or Xbox360 yet, so it may take a while, but I will probably get it.
I would have preferred that they didn't bring Star Wars characters of all things into the game, though. I am not such a fan of Star Wars that I am excited by the idea of controlling them in a fighting game, and they just clash way too much with the setting and characters of Soul Calibur for me to think of them as anything but an annoyance. I really hope that they don't show up in the normal game modes...
