On paper, this looks like quite a good, balanced line-up, with a nice mix of IP attractions and in house concepts.
Vulcan Peak sounds the most interesting of the two new additions to me. At a guess, I'd say this is going to be in The Jungle area of the park given the use of the word 'Vulcan' which can refer either to the name of the Roman god of fire, or the fact that it is the latin root for 'Volcano', suggesting a possible link to Nemesis Inferno (somehow I doubt it has any relation to the Vulcans in Star Trek though - sorry sci fi fans
With The Walking Dead: Do or Die, it's going to be interesting to see which part of the TV show they choose to use. Given Living Nightmare already uses the Negan storyline, I wonder if they will do the maze as just a generic TWD theme, or use a story from an earlier season.
I love that Thorpe are introducing scare zones. Although Thorpe have had roaming actors in the past, these haven't quite worked as well as they could have done. Having two proper zones offers the potential of really building the atmosphere around the park - something which has been missing in previous years. Interestingly, the teaser image released tonight may offer a clue to the theme of Amity High with the words
"Recent reports coming in of multiple teenage bodies found behind the old speedway with strange marking on necks"
To me, this suggests Amity High may have a bit of a vampire theme going on as that would be the most obvious conclusion for a horror based creature that leaves marks on its victims necks. The Big Top Showtime has the potential to cause the right kind of chaos in its zone - clowns set on the loose is pretty much a classic concept which will hopefully work well.
The only main concern I have is the return of Blair Witch. As others have said, this was always a weaker attraction, I'm not sure quite what they can do to add to it given the limitations of its location.
Hopefully we'll get a few more clues as to the exact story of each attraction in the next couple of weeks.
