The Waterhole precinct (or trail) that was planned to be constructed at the same time of the elephants has been scrapped which does indicate the priority as of right now is/was the elephants and will be the gondola next.
The Waterhole Precinct was going to provide new facilities for some of the carnivores (Spotted Hyena, Cheetah and African Wild Dog) and also a new Safari Station with a new Meerkat habitat. This all hinges on moving the Camels and Scimitar Horned Oryx to another habitat. I'm not sure what the intention is there.
