The voices in the Leipzig presentation are stub voices from two Belgian actors - we use them to test out our voice/lip synching pipelines but they won't be in the final game (except perhaps as an easter egg as there are some really funny ones in there because of the accent)
I'm sure it be very humorous like the dwarf and human that argue over a wagon wreck in Divinity. For some reason that is my most memorable moment listening to them argue.
Every time I run into a problem on the road... a dwarf is at the bottom of it! (or something very close) NPC's arguing with other npc's is just too funny.
