These teasers have been going on since the farewell 2019 from Thorpe Park YouTube video starting with a teaser saying initializing 2020. Then on a top 20 reasons to come to Thorpe park list by the park themselves, it says this on number 20:

20. In 2020, we’re initializing...

WATCH. THIS. SPACE.

Then a picture was leaked at a Thorpe Park 2020 plans conference. It showed a picture of a futuristic kind of background with a bunch of large humps saying 2020.

And now we have this:

Any ideas what this could be? I’m guessing a new coaster. It just makes the most sense for this much teasing. Maybe an RMC?

Though I've never been to a theme park outside of the United States, Thorpe Park has always intrigued me. Colossus looks amazing and The Swarm was one of the first Wing Coasters built. Slammer also looked awesome to younger me, but sadly it has been dismantled. I'm sure whatever comes in 2020 will be equally fascinating.

The nature of the teasers makes me feel like it may be something similar to Smiler at Alton Towers, but I'm not sure how well that ride's reputation recovered after the incident in 2015

Maybe an Intamin mega coaster or a B&M hyper. The leaked presentation slide had large humps in the background. Large airtime hills? It also had a theme of some sort of futuristic technology.

We have this now:
 

We also have on the stealth post and this post #ThOrpEpaRk.

All the capitol letters make the word toer.

Toer means something ROTATING on an AXIS.

My guess for Thorpe Park 2020 is that they are getting an S&S axis.
