Hello and welcome!Hi! I'm new here.
Some time ago, I had heard somewhere that datamining had found that the limit of space in the zoopedia was 200 species. I don't know if that's true, and it doesn't mean that the developers aren't going to extend the limit, but let's assume that it will stop at 200. That would mean that there would still be 34 places available, enough to make 4-5 additionnal packs plus one animal for the game's anniversary.
I think we've pretty much covered everything we could hope for in terms of decoration. So I'm assuming that most of the remaining packs will be animal packs and not decoration packs.
Based on that, I hope we'll have a mountain pack with the golden takin and the Pallas cat, which are my top picks. A coastal themed pack would also be nice. In particular, I'd like to have the walrus, which is number 1 on my whishlist. A forest pack with the Tasmanian devil and the wild boar. And finally, I'd really like a birds of the world pack, with at least ten species of bird.
I'm pretty sure that the animal limit is gone with latest update
