They talked about Miles Ekhart who was the Quest giver in the 3.0 demo
Miles took about three weeks from shoot to implementation and this was the first time they'd done a cinematic quest giver like miles using the new tools and bug fixing those tools along the way.
It may take only two weeks per quest giver like miles and that was a generous time scale they said.
Miles won't be the only cinematic quest giver for 3.0 as they're scheduling another shoot specifically for 3.0.
Mile's eye movement during interactions was the actor himself trying to be sketchy, the IK Look system has only the on/off feature and they're working on having it blend naturally so the AI's focus is on you instead of in your general direction.
Francesco Roccucci talked in depth about the Subsumption system, I highly recommend you watch it as there's too much detail for me to summarise properly
Subsumption is a collection of systems that include behaviour of characters, missions and is what connects it to the games code.
The goal for subsumption is to make AI as life like as possible and what a player can do or go, so can an AI. Ship repairs, manning a console, etc.
The amount of AI in an area depends on the area itself, small enclosed spaces wont be packed, but larger spaces will have more AI.
The intent is to LOD AI to allow a large amount on screen at any given time, the physical model is what limits the amount, not the AI actions.
Currently they can have up to 40 AI on screen at any given time without optimisation.
