Aaah, ok -- so there could be some fixing of bugs, deeper interactions with the companions / some cutscenes, improved mechanics, and then, at the end of the list, possibly act 1B? What would that mean, btw? Crossing the Lake and Moonrise Towers, or just "crossing the lake" and exploring the Underdark road right before reaching Moonrise Towers?

It's not so much about managing expectations as it is about managing disk space.
