I can't wait to see what they'll look like, appearance-wise. I still hope Sonya has some sort of a Big Mama appearance to her. Just hope that her outfit this time is actually something worth liking. I never really have cared for anything that she has worn.
With Johnny, despite that he got serious towards the end of the story, I hope that he still has his sense of humor (not doubting it or anything, but it's still worth it to say something). Just that, I'm going to be laughing and be disappointed at the same time if they randomly ditched his chest tattoo if he's showing up shirtless.
Game-play wise... I'm hoping both will be really fun to play as. So far, not a single character yet has shown me anything to dislike about them, so I expect a good show whenever they get released.
No, she doesn't. There is all but one move that she has of her own.
