I recently called a castmember to ask about something else, and expressed disappointment over Club Villain not returning this year. The castmember's direct response was, "that's not what I understand". 2 weeks prior, toward the end of July, I asked a castmember about CV coming around back for the Halloween season this year. She said, "Put it this way, I'm 99.5% sure that it will". She also told me to look for it "closer to October".
Now that doesn't mean anything. Castmembers aren't infallible, 99.5% is not 100, and we've still seen no credible evidence for a CV return.
It makes me wonder though. Maybe they planned on bringing it back, and then axed the idea. Or maybe they're still planning on bringing it back, just not this Fall.
