Let's just stop and think about all the free/temporary/going to be free enclosures that the zoo has at the moment:
First up is the former cassowary enclosure that seems to be made into an enclosure for a cat species.
The old bongo/banteng paddock was holding an onager stallion last I visited. It may remain there until we get a new ungulate.
Once the binturongs move to Islands, that enclosure will be free for a new species; hopefully a large carnivore.
The old anoa island is currently home to some babirusa but we don't know if this is permanent or not.
The serval enclosure is housing the female cheetahs but that could change when yurt is finished.
Condor cliffs is becoming a new Europe on the Edge so the old Europe on the Edge could become a major new enclosure (please don't make it a new picnic lawn or playground).
The sun bears will move to islands leaving an empty enclosure in SoJ but I think that they will make it into a jaguar enclosure again.
Also, when the Malayan tapirs move that will leave us an empty paddock in that old cattle house.
The giant anteaters will be moving to Bears of the Cloud Forest so that leaves yet another free enclosure (two if you count the round enclosure).
The old midwife toad enclosure is still empty. I am hoping that it will soon home a native reptile/amphibian.
The former warty pig paddock has been made into an expansion to the spotted deer paddock so I think that it is unlikely we will get anything new in there but you never know!
The aquarium in EoAF is still empty I hear. I hope we get some good fish in there! The former whip-tailed scorpion viv in the Fruit Bat forest is still empty as well.
The rainbow aviary (or the "forgotten aviary" as I call it) should be ready for stocking once this wretched bird flu is gone.
And finally (I think) is the old capuchin island, but would I be right in thinking that the gentle lemurs will be moved there?
So I think that's everything!

If I have forgotten anything then please let me know.
All in all, the only thing that I can say is that we could be in for a very exciting year at Chester!
