The epicness of the game is so high right at the beginning that we'll probably loose an important part of such a game : the feeling our characters slowly become powerfull and that the story gains in intensity.
Story, visual effects, creatures, side quests/companions quests, world design, gameplay, cinematics,... They want our excitement gauge to stay at maximum all the time... As a consequence, I think the feelings we'll have playing the game are going to be very linear without a lot of surprise or emotional involvment.
We'll have to deal with it, guess it's Larian's style.
