I visited the studio store recently (they have a lot of horror displays and merch; go see for yourself--I posted about it on my social media), and I asked them about Horror Made Here. They admitted it was well liked, but said there's a lot of reasons why it hasn't come back. She didn't get into details, but it sort of hinted it probably wasn't coming back. I'm guessing it was too big of a disruption to both filming and their usual studio tours.
