There were 120ish Spells in BG2. Make it 200+ plus abilities for BG3 all in line with D&D.
Reactive Day/Night cycles, with dynamic quests based on when and where. Amazing next gen weather/atmosphere effects.
A boat load of creatures. There were already HUNDREDS in BG2. Make them super accurate from the D&D world. No level 4 Dragons.
Even more branching LONG and INTERESTING dialogues with a MULTITUDE OF CHOICES and impactful decisions on the world.
EVEN MORE super interesting multi-branched quests.

All great suggestions, except the FUNDAMENTAL problem with turn-based is that suddenly you can never have a battle with more than ~12 participants without each turn taking half an hour. They either a. didn't take this into account (unforgivable dereliction of duty for a game designer) or b. don't care.

My money is on B, which makes it all the more frustrating that they pushed so hard to be the ones to make a Baldur's Gate sequel when they didn't even bother to try doing it justice once they secured the rights.
