I don’t foresee another return to the Americas, however, I can see us getting another generic “round the world” pack that can add animals from the Americas.I am also very concerned for the Mara. I suspect the next pack will be a return to an old world region such as East Asia or Africa or a theme that not many popular South American animals fit into like islands or costal. Personally I think the Coati and Squirrel Monkey are the most likely South American animals left. Hopefully we get the Mara in some sort of scrublands pack.
I personally foresee a Safari type pack. However, these last 3 DLCs have all been “popular or long requested” themes. If we do get another DLC I can honestly see something that’s been long requested, like the Coastal Pack.
