The online proposal is curious.
It mentions the new coaster as some form of launched shuttle experience:
A new rollercoaster – guests will be propelled on a car through banks and turns before coming to a dead end on the track adjacent to a themed structure on the southern part of the site. The car will then be propelled along the same route back to the station located on the north east part of the site. A hard standing ride maintenance area is to be provided adjacent to the ride station.
It also suggest that it will be a family coaster:
The emerging proposal for a new themed Amazon Land includes a new family rollercoaster – the first at Chessington for 17 years - and two new children’s rides. This investment is critical to the Resort’s recovery from the impacts to the business from the COVID-19 pandemic.
This image also shows how the layout above would look outside the park:
These sort of mockups usually feature within planning applications. I'm sure they're done for different / not-final layouts too, but it seems odd to show one to the public for a not-final layout.
It very much feels like there's a disconnect between what
@Jared heard at the consultation itself and the details on the website. Obviously I could be getting the wrong end of the stick, so really not for me to draw conclusions, but a (weird) family shuttle launch and a 1.4m winged seat coaster do feel like very different things.
Nothing stopping it being some weird, winged seated, launched, shuttle experience either. But family vs 1.4m restriction is a weird one.
In any case, if it is some sort of shuttle coaster, I think the immediate thought that jumps out is 'Throughput concerns'. Aside from that, I think it's still too vague to make any further judgements, but I do get that it feels a bit hollower compared to some of the original, vaguer concepts thrown about.
