My questions would be:
1) Will you show us some plate armor models? With the corresponding gauntlets and boots for them? Are the issues of the armor not aligning correctly and leaving gaps, something only seen in EA's incomplete models, or is it a design decision for aesthetics and thus, will affect the whole game? I assume not, but i have to ask, sorry :3 . We saw some datamining from early patches showing pretty awesome armors, but then something happened, the models were altered and they looked... wrong, unaligning etc. I still have no idea if this was only in EA and it's not an issue, or they were changed on purpose, to correspond to other models you created for said armors, but have not yet shown. So in general, a look in plate armors, who were completely absent from EA, would be appreciated. As eye candy.
2) Will you tell us what races and subclasses should we expect? Are we going to see some fan favorite subclasses although not in PHB, like Hexblade, and some races like Aasimar and others? I don't have a problem actually, but it would be nice to know, because i am reaaaaally slow with character planning :P
3) Is the final game going to sport actual cloth physics? Like the cloths from robes or cloth pieces from armors or chains actually moving with the wind?
4) Are you going to show us a multiclass character, and how multiclass will work in BG3? Should we expect the exact same thing as in tabletop 5e(with multiclass spell slots for example).
5) Is the game going to have only some basic armor models, like the ones we have seen, or are there unique armors and items as well? Like in BG2, you could craft the hammer Crom Faeyr, and the Red Dragon Plate armor etc, is there something similar? And since this is leading to Grymforge, will be able to craft adamantine plate as well there? or just Splint?
That's about it :p
at least the robe physicals is confirmed. in the city view demonstration video, you see Gale's robe is swinging when he's jogging.
