We got Blade Mode Cancels :D
After hearing about this yesterday, I literally spent two hours in the demo coming up with some combos. Also some stuff the demo doesn't tell you:
Forward Forward + Weak Attack is a launcher, Forward Forward+Heavy Attack is a rushing impale move, Forward Back + Weak is an energy blast, and Forward Back + Strong is 360 breakdancing sword spin move. Pretty slick if I do say so myself.
