Um... no. 2023 has always been the 50th. The event's first year was 1973, NOT 1972.
As for Scary Farm 2022, the event WILL have at least TWO new mazes this year. One of them being the Paranormal Inc replacement. The other maze will be an additional maze in a NEW backstage location (Ride GhostRider, look to the right.. the maze plywood platform is visible).
Mystery Lodge is once again NOT being used for a maze this year (just what I've personally heard, but its still only May)
As for Fiesta Village's entertainment, you're reading too much into it. If they use it for Spooky or Scary Farm, it won't be touched until late July/early August. But I still wouldn't expect anything major in that spot considering the small footprint.
