With COVID they're going to have to prioritize- guaranteed they can't do all they want to do, maybe they're operating at half, maybe 3/4, maybe 1/4 nobody can really know but I think we can all agree they won't be able to be as efficient in what they're doing, which in turn is going to mean a mix of pushing things back and cutting things at least for now.

The Haloween event sounds like one such cut, and I'd expect aesthetics not tied directly to necessary content to be another. That might not make it suck any less for those looking forward to more genders for the new races, but I think it's at least a pretty straight forward reason and there's little reason to believe that's not considered a low priority item on the list.
