Here's the full post from the article:
The ride starts with a simulated lift journey deep into the bowels of the earth. From there riders enter a cave where riders are faced with one of four drop rides. These are pretty much the same as those used in Merlin's Dungeons attractions, so are about 8m (26ft) high with a drop of around 7m (23ft).
All four drop rides look in on a central area that will eventually be home to a centrepiece, but the design has not yet been revealed. It's imagined that some sort of show will take place before the drop, and it would be hoped that the drops would be kept secret. After the drop, riders exit at the bottom and go through another "lift" to take them back to the surface.
Overall it sounds like it it could be a really exciting ride, and the idea of starting a drop ride at the top is something that has always been appealing.
There is a photo attached to the article, I don't have access to it but I've had it described:
It is of the upper floor. It shows a central platform with the tops of the four towers sticking above. So it is likely that you will enter on the top of the ride, then drop through the floor to a show room at the bottom, where you then exit.
