YEA BABY!!!!
I got a challenge, let's talk about the worst outcome possible for a SA pack, only rule is it has to be a scenery or animal pack.
Neotropical Pack
White-Tailed Deer
Tufted Capuchin
Andean Moutain Cat
Kinkajou
(Exhibit Animal) Gray Wall Jumping Spider
(edit: wait we have not been promised a dlc yet

!)
Staying with what i think still is a realistic outcome
-Bear
-Ocelot
-Tamandua
-Guanaco
-Exhibit
My reasoning: While every one of these animals is a perfectly fine addition imo, this constellation is probably the worst one for me (Thats still a realistic one for Frontier to make).
Having no monkey is an automatic dealbreaker for any SA pack in my eyes, and since Frontier seemingly avoids them at all cost i think its unfortunately still possible for them to ditch it in here aswell.
But since we pretty much religiously have atleast one new rig animal in each pack i chose the tamandua here, not because its bad or anything but because out of all the animals that would require a new rig like the porcupine, monkeys and some birds its just the weakest for me.
The bear and ocelot (any cat really) are here because having both of them in this pack would is just the wrong choice ontop of PZs already carnivoran-heavy roster. Having one of them in such a packs i think is all but guaranteed tho.
Lastly the guanaco, i think its also pretty certain that we will see one representative for southern SA in such a pack and out of the big 3 (Rhea, mara and guanaco) its just the weakest choice for me.
