@Mr Gharial Currently they only have two large primate species left in here with indoor and outdoor exhibits, and the mandrill group is dwindling as the animals age and pass away, so it seems they are phasing that species out and keeping just the spider monkeys, which might move to the new jubilee complex in a few years (depending on how much the plans change). They do have several species of callitrichids left in all indoor, but decent exhibits.
After the new jubilee complex I think this building will likely be next. A small mammal house with small primates, perhaps one monkey species (I would still like to see L'hoest's monkeys return to Antwerp, given they were named after directors of Antwerp Zoo), and hopefully a return of some form of nocturnal exhibit would be my preference for this area.
