Adding onto what has been said, as
@Brian G. mentioned, nothing has been confirmed nor denied. It's truly best to wait and see what's actually coming, sometimes the rumors are correct and sometimes they're not, it happens. But if we're going off props that have been set up, it's very likely a clown zone will be in Hollywood and perhaps a Cemetery zone is in New York.
The only thing I don't get is why some folks are thinking that KKfOS potentially isn't happening because the clown zone looks to be in Hollywood. That's one of the larger zones, which has more than enough space for the rumored clown mash-up. Not to mention Hollywood has had mash-up zones before such as Lights, Camera, Hacktion in 2021, which had a bevy of different characters of all shapes and sizes.
And while HW may not be as spread out as NY, when you think about it on the flipside, a tighter cluster of clowns could make for some wonderful chaos. Either way, HW has more than enough space for a mash-up clown zone that includes KKfOS, especially when you consider that KKfOS's zone in 2018 was in a much smaller space on South Street! Space is just not an issue here for the Klowns.
