This is my copium theory as well hahaTbh ‘Old World’ is the only suggested theme that really fits all of the clues we’ve had so far. I reckon it’s likely we’ll get Old World and New World Animal Packs in very quick succession of eachother as a way to round out the roster
But idk, i don't see them naming a DLC "Old World" animal pack. Plus the tree kangaroo and the echidna doesn't really fit with this theory.
Like @AndyZoos said, the thought of a "collection" pack the fills the gaps in previous DLCs is really nice.
So far we have:
Arid/Africa: Baboon... and maybe secretary?
Eurasia: Markhor and Palla's cat
Oceania/Australia: Tree roo and Echidna
For the Tropical pack the want at the time was for coati and NWM. Grasslands was pretty much perfect but people theorized the secretary bird for that one as well, though Emu was the priority (although the secretary and grey crowned crane were both mentioned for the speculation of the Conservation pack). Barnyard was suspiciously missing a duck. Aquatic could've been the perfect pack for a Pelican (Wetlands as well). Twilight was missing the devil and the kiwi but that was fixed later so while there are some animals that could be a good add-on to that pack (like the aye aye or the ocelot) i think is pretty much fine as it is now. Arctic choose the wolf over the arctic fox that was later added in the NA pack, but the musk ox was also a big miss. The walrus would fit for that pack as well, though the possibility for pinnipeds came later.
So idk. Would be nice if they are trying to "complete" what we expected for those packs and what we feel is still missing but then we come back to the dictionary and the freaking dik dik and sifaka haha
I'm curious about what the theme and rest of the roster will be.
