First of all, I realise this suited to 1.8 Discussion and Discoveries, but I felt a new thread was needed for the vast subject that is NPC Villages.
Now, to the topic at hand;
Does anyone have any theories about how they will be implemented?
What will happen when you kill a villager?
Will they respawn?
Will they die forever?
What will they drop?
How will they react to different types of violence?
How will we trade with them?
What will they be able to do by themselves?
How far will they expand?
Can you be accepted into the village and given protection?
