With regional packs back on the menu maybe, maybe, maybe there will one day be a "Central Asia" pack with wild boar, saiga, pallas cat, and dalmation pelican? (Probably not, but I can hope, right?)
It would pair nicely with the India pack proposed by PnGLINNyo and a highlands pack (takin, marhkor, pheasant, hyrax, baboon/gelada, spectacled bear, bar-headed goose).
The wolverine I think should be kept for headlining a Tundra Pack - wolverine, walrus, muskox, tundra swan.
That leaves the always neglected South America, though I could see a Treetops Pack (spider monkey, colobus monkey, tree kangaroo, ocelot), a Children's Zoo Pack (dwarf goat, squirrel monkey, muscovy duck, coati), and a dedicated South American Pack (howler, tamandua, rhea mara, peccary, turkey, scarlet ibis) all being applied to this area.
Add ABB and greycrowned crane as anniversary animals and things would be looking pretty darn great... but there are always more animals I wouldn't say no to, and I hope support continues as long as possible.
