I feel like a European pack is a must at this point, and maybe the only pack I can see "for sure" being done. It may not be next, but we don't know what may be next. We can speculate and want Aviaries but who knows PZ may not even go that route at all. They've at least gone the route of Locality and to an extent Biomes. We can guess at Biomes but I think with all the other continents covered, Europe has to be coming soon. I'm thinking the first 2022 pack because if it's for December that's four locality based packs released back to back. I just don't see that happening.I think another factor is the following: how likely is a European pack?
I see rumors saying that it'll never happen, which doesn't make sense, really.
Now, I also noticed that they're sneakily adding in European animals through other packs. NA gave us the moose, Arctic gave us the reindeer (polar bears are occasionally in Iceland, but that's not their natural range, right?)
Aquatic gave us the gray seal.
Plus, we have the gray wolf (unless they rename it to a specific NA subspecies) and we have the American look-a-likes of European species (bison and beaver).
So, what do y'all think?
