1. Tasmanian devil: I still think it will come, even though it's taking its time.
2. Manul: honestly, nothing I was really hoping for, but as said by others, the fact we got a new small cat rig and it being quite popular, give me the feeling we'll get it.
3. Spectacled bear: also a species that is taking its time, would have expected it a bit earlier, but also very low on my wishlist
4. Takin/markhor: I can definitley see one of the two coming, but I'm not sure if we will see both
5. Wolverine: it may would need a new rig, which could be the main problem, but still, I can see it coming
6. Gelada: my biggest wish for this list. The fact we didn't get a baboon in either the Arid or Grasslands pack could mean that they saved the Gelada for a Mountains pack, or that we simply won't have any "baboon" at all, I'm hoping for the former.
7. Tanuki: another quite popular species, which probably wouldn't need too much effort to be done
Honestly, I can't really think about other species. Pelicans and other waterfowl are unlikely due to the rig, galliformes could reuse the peafowl rig, but they could have done that already, new world monkeys (specially a spider monkey, as this would need a new rig) seem unlikely too, the same goes for tree kangaroo.
I would definitley bet on more antelopes, but can't really think of any packs to include them...
