Do we have the exact number of species in JWE3? The Steam pages mentions "over 80 species", which could be 81 or 89 for all I know...Has anyone ever calculated how many percent were scratched from JWE3 (as far as I know) compared to the overall roster?
Anyway, if I'm counting correctly JWE2 had exactly 79 species in the base game plus 5 in the Deluxe upgrade pack, so those numbers are not wildly different. We may start PZ2 with barely more species than what PZ1 had on release, but I wouldn't be surprised if there was a far higher percentage of habitat animals (if not a fully habitat roster, considering how exhibits have been scrapped from recent releases and Frontier might have completely lost interest in them). Obviously, there's also the relatively high possibility of new flying and fully aquatic species replacing some of those we currently have, and I expect some of PZ1 base game species to be replaced by more recent or entirely new ones (kangaroos, koalas and polar bears sound more essential to me than African wild dog, spotted hyena or Himalayan brown bear for instance).
