Called Disney reservations to inquire about several things, including Club Villain. Here's what I got: Club Villain has neither been confirmed, nor ruled out for 2017. The cast member also told me that it had been removed from the reservations listing, which is unusual if they're planning on bringing back an event.
I was given a feedback email (guest.services@disneyworld.com), and was encouraged to write WDW regarding my interest in Club Villain.
