If we're still on NA, I mentioned the ABB as high profile and the Wolverine as popular but not solely NA. Still, I'll include it.
We don't need a NA focused animal pack again since we already had one. Scenery would work.
Woodlands Scenery pack: Log Cabin building theme.
Wolverine
American Black Bear
Wild/Domesticated Turkey
Elk (Wapiti in Europe) - really like the suggestion of it over the White Tailed Deer
Flying Squirrel (either Northern or Southern species) - WTE
Other somewhat potential candidates include the North American Porcupine, Walrus, Muskox, North American River Otter, Coyote, Black Footed Ferret, Rocky Mountain Goat, Bighorn Sheep and Canadian Lynx. And more habitat appropriate birds like the Greater Roadrunner, Roseate Spoonbill, White American Pelican, and several species of Goose. I'm just feeling like the five I picked seem either a bit less likely to make it into the game.
Not to mention the Central American animals that happen to extend to the southern part of North America like the White Nosed Coati and Ocelot, though I'd prefer them in a dedicated Latin/Central American pack.
Other potential themes that may change up the animals are the American Wild West or Native American type of themes.
Either way, there's actually enough picks to make 2 scenery and 1 animal pack listed right here. I just don't think we'll get more than one Stealth North American pack, as well as a dedicated Latin/Central American pack.
