I do have one question about the trailer are we getting the female goblin as a companion it does look that way to me maybe not in the demo but when the game is fully completed
I think they could do better for origin companion, than a weird looking female goblin, I would rather have a badass orc barbarian or githzerai or some other monster as companion.
Of course extra playable races are always nice, whatever they are...
On the other hand this goblin got an awful lot attention, so it is possible..

I think the female goblin is just an npc for the game, who is related to some bigger quest.
It would be nice to see, some important cool npcs as well, that appear in multiple stages of the game to make them more memorable.
