Why isn't Universal doing some sort of halloween event like knotts this year. Just curious

While Universal has some decorations up throughout the park.... they once again will not offer a themed evening like Orlando. They haven't done this for years, and I think it is partially due to the fact that Knott's event is so well done, and is known as "The" place to go for that type of event. (Yes, SFMM offers Fright Fest, but how many threads does it have?)
