That Phase-4 chick looks pretty sweet. I doubt she'd be THAT hard to use. I mean, it'd be awesome if she wasn't so easy to where you could do jumping jacks on your controller and make combos happen with your feet. I'd definitely be hype for that, personally. From the few combos they showed, it looks like some timed attacks may be necessary. Not just frame, just not mashable string type stuff.
On another tip. I would've liked to have seen her have a different hairstyle and color than Kasumi. Just so she wouldn't look JUST like Kasumi. But, that's what a clone is I guess. Just would like some sort of individuality between the two besides moves.
