Billie Eilish is so far the only house that's been strongly rumored to have been scrapped, that's one house.
As for the fate of Brides and Tooth Fairy, right now that is easily boiled down to "Are they staying/getting refurbished?" or "Are they getting replaced?". There's not a lot of speculation to go off of those, and if it ends up the former, then the speculation is zero.
As it stands, that is not enough to justify starting a speculation thread as well, let's face it, it goes in aimless circles when there's little to speculate on. One house won't cut it, and the other two are essentially a 50/50 discussion point.
