I have heard talk of bringing in three white rhinos, although the locations and timeline on this are quite vague. However, rest assured that things are in the works, as only Shaboola is left.
Regarding the tapir, there has been talk for several years now about bringing a female up from the Bronx Zoo. However, there are currently concerns about our ability to manage two individuals if they do not get along (especially in winter), and even more so if they end up breeding.
