so is that possible toward moonraise towers this time before arriving baldur's gate?
Nah ... or at least not likely.
As stated abowe:
Patch 8 game will have 104GB ... but curently the game have 100,2GB (at least on my PC) ...
Meaning cca 36GB of the Patch will be just replacing old asets ... and the rest 4GB will be new things ...
Also keep in mind that some asets (cinematics, models, sounds,...) can be quite big compared to others.
If i would have to bet for new content ... i would say we might get acess to that crypt behind grymforge, that is quite small area, but its some new content and its kinda hinted by those statues on PFH post on twitter and Larian homepage.
But besides that? Few spells, some new armor, and i would not expect much more ... at worse, you can be pleasantly surprised.
