I think there is a difference between "It kinda sucks that the IP rumors I'm most interested in are getting shot down" or "I'm not personally interested at all in this rumored lineup" and "This IP lineup sucks and let's move on to next year." It's subtle, but it is there.
No one can know if the event is going to suck, because there is literally 0 information about it other than there being an Orange shirt with the logo on it.
Also, technically most houses at this point will be repeats. It mostly just depends on how long the gap between them ends up. Nightmare and Friday are "Repeats", it's just been so long it doesn't feel like it to most. Insidious was in Orlando in 2017, which will be 7 years ago as of September. Only three less than NoES. Think about how many people have hopped on the HHN train in that time. No matter what IP they choose, even if it ends up as TCM or Halloween or Purge again, it'll end up fine.
