I think a majority of the hype of CGY was people hearing the name and thinking there was gonna' be a bunch of actual carnival rides in the house. Personally I really enjoyed it for what it was as well as it's more open scenic concept. That said, I think there was more hype going into LT: TWE. People were freaking out when that house was revealed.
Now speaking of possible returning houses/concepts. I think it's safe to speculate Scarecrow is returning, especially when the PR had a picture of it. Now I'm noticing a good chunk of people hoping for a open concept a la' Carnival Graveyard for it. In ways I can understand, since it would be fitting for a cornfield. However, would that open concept take away a claustrophobic setting/feeling which the original had? That type of setting is perfect for scares, so losing it might be a lil step back in that regard.
