I havent heard of anything that proves that the actual expansion is less than 3 hours in time i think they will try to squeeze 8 hours in it. Plus they announced some new monsters that are being released. They have already released 3 hour expansions with all the notice board and from a different sky quests. I honestly dont believe that they will only add 3 hours of gameplay most likely they will try to add at least 5-8 hours.
