I wouldn't be too surprised if they brought back last years ST house and even if they did a KKFOS in 3D house, simply because there's precedent for it. When the house count went up from 8-9 at 25, up to 12 now, they brought back 2013's AWIL and built the Alice 3D maze. Plus the history of turning zones to houses. Real question would be if they really think having 2 ST mazes would be a draw or would people think it's lazy.
