Exactly, in Heroes 4, for example, the dwarves made golems, and the mages only animated them.
The developers have a unit recruitment scheme:
warrior-archer-mage-cavalry
This results in 4 units, and then it's easy to add the remaining ones; usually, developers of turn-based strategy games stick to this scheme.
By the way, there will be shamans, and they will be male, but they are not the only ones who have changed gender. Another elite unit, an archer that was in Heroes 5, will also be present. It's easy to guess that in Heroes 5, the only archers among the orcs were centaurs and cyclops, which are already known, so I think it will be something like this:
Core - Goblins, Harpies, Ravagers
Elite - Shamans, Centaur-like archers (my opinion), a new unit
Champion - Cyclops
