Sakurai has confirmed that the female villager from Animal Crossing will be a playable character in the forthcoming Smash Bros for Wii U and Nintendo 3DS. She’s not a “new” character, but an alternate costume for the male villager. He had this to say.
“Pic of the day. You can choose to play as the girl villager too!! How lovely.”
Not a big surprise, there is a Male Wii Fit Trainer, so a female Villager makes sense to.
