I'm annoyed that they've reused Cammy's assets so heavily. I realize that it fits the storyline, but I'm still annoyed. I wish they would've at least changed her neutral standing animation. That said, despite my disappointment, her moves and playstyle actually seem quite unique and interesting. I bet she'll end up incredibly fun to play.
I'm still looking forward to Poison the most, but at least Evilcammy looks intriguing. Poison was the one thing that I truly loved about SFxT... the entire time I played that game, it was basically just to play her. And the whole time I kept saying to myself, "she really feels like a SF4 character."
