I'm not sure what to think of that video. I really like some things about it, but some others discourage me a little.

I like the side-dashing that Pyrrha shows off. That could open up a lot of opportunistic strikes and if it is a new mechanic for everyone, then you'd really have to be a lot more wary of those kinds of flanking attacks. Pyrrha looks like all the best parts of Sophitia and Cassandra combined. I'll definitely be playing with her from time to time. Old Mitsurgui looks badass.

On the other hand, I'm not a big fan of the introduction of what appears to be supers. On Joystiq someone mentioned it also looks like they're bringing in Ultras, but those are just more advanced Guard Impacts, which are then followed up with a combo and finished with a taunt. Certain Soul Calibur characters have had more impressive Impacts since SCIII. Seigfried has always had one (the triangular stance with his sword flickers briefly). Cervantes, Amy and Raphael have a few as well. Setsuka has like five.
