I don't know, I know that one of the bosses is Ursula but other than that, I'm not sure. I know you can go to France and play alongside Quasimodo and Esmeralda but again, I don't know. Can't wait for it though. Super excited.
I have seen people playing the demon online and it seems the used both the circle pad and the D-pad. I don't think it'll make you play with circle pad pro (whatever that is) because honestly, the 3DS ....bigger version (whatever it's called) is going to be too new and Nintendo knows that most everyone will have the first 3DS so they aren't going to screw anyone over with that.
