Looks like it will be a New World pack, the species choices...
Coyote: totally not interested, I guess the reason why the Frontier offers this is that, few days ago a Modder announced a decent work of Coyote, and the Frontier just "robs" the attention and market. Otherwise, Ocelot is definitively better pick for New World small carnivores, we have enough NA canids since there are 2 wolves and 2 foxes in the game already.
Rhea: fine with it since we don't really have New World birds yet
Flamingo: not a bad pick since there are several demands of New World Flamingo, but I would prefer Roseate Spoonbill
Saki: fine with it, since the game really needs more New World monkeys, the higher-demanded Black Howler and Geoffrey Spider Monkey require more animations, the Frontier is still lazy as usual.
Bighorn Sheep: WTH is this pick, we already have Dall Sheep, this is too lazy pick. Why not give us Musk Ox?
If this pack doesn't offer Coati and Patagonian Mara, then it will be my least like pack ever of Planet Zoo
I guess this pack will offer 7 species like previous Farmland and Zookeeper packs, so 95 scenery pieces with Wild West US and early-modern Latin American themes, and no exhibit species.
I would say the financial hardship that Frontier suffers is way more serious than what I previously thought. I also heard the sale of Planet Coaster 2 is not successful. So the Frontier doesn't have enough resources to work on new models, and they have to make more easy copy & paste species. So don't expect too much on future upgrades or Planet Zoo's 2nd generation.
