I'm pretty sure we're currently missing the rest of the Risen Road Area and the whole Mountain Pass with resolution to Gith creche quest plus Moonrise Towers.
And I've also read a confirmation of 3 Acts somewhere, with ACT 2 being the largest.
I'm guessing Act 2 will be Baldur's Gate, and that apparently is going to be huge
Act 2 is Moonrise towers now whether you go there through the mountain pass or the underdark that remains to be seen.
There seems to be at least 3 top way roads and 1 underdark road to reach there.
Baldur's Gate could be Act 3 or 4... who knows.
