I mean, we have been recieving high-ranking META-wishlist animals ever since Africa, I do not see how could that possibly mean the end is near? If anything, Twiligh and Arid did not recieve much in this regard.
Africa - Meerkat, White Rhino, fox species, hot-climate penguin
NA - Moose, Cougar, Alligator, Beaver, Sea Lion
EU - Lynx, Alpine Ibex, deer species
Wetlands - Capybara, ASCO, Platypus
Conservation - Amur Leopard, Przewalski Horse, a gibbon species
Twillight - Common Wombat, Bats
Grasslands - Maned Wolf, Emu, Wallaby species, Caracal, Armadillo species
Tropical - RR Hog, Fossa, Lar Gibbon, Sloth
Arid - AC Porcupine, Dromedary
Of course, the rest of the animals will always be wanted by someone, but I do not see this trend of recieving high-wanted animals just now. We have always been recieving them.
