That's the thing the Hopper's Cabin and Starcourt are pretty much two of the important parts that are best in the house, so I don't think they'll add much which is fine but people get to see Demodogs but also a glimpse at the new creature from the new season, it's like what Horror Nights said that yes it will be sorta like Saw Games Of Jigsaw which definitely fits. As for making another house? I mean it comes into the question, this season pretty much answers a lot of questions, so we might just have to wait for the foreseeable future on what the Duffer Brothers are going to do at this point. I'm sure if we get a season 4, we'd definitely get another house for 30 but I'm not holding my breath much on it, I think Universal will be wanting to find other ips in the wings waiting to bring to the event next year.
