May I direct all of you to this ol' thread I made quite a while back, for the people who may not have seen it:

As all of this stuff is slowly getting revealed, it's quite certain that the rest of the stuff is coming with the game as well, like the two companions and maybe those two talents for elves and ancient ents.
Quite disappointing that all the interesting unit possibilities, like the orc hunter/goblin shaman/faun/infernal dragon...they're just recolors. Oh well, I am loving all this new content!
Also, those aren't orc veterans.
You can see in the battle log. They're "Orc Trackers". Damn, they aren't archers! Also, I'm pretty sure that the alchemist recolor are gonna be the engineers. Just a guess.
Very exciting stuff!
