The release date is already reassuring. Too bad that no group of 5 or 6 was shown and / or multiclassing. Would also be too good to be true, until the release with larger group and level 6 for multiclassing in two subclasses to experiment with the already accessible game content. But maybe there will be a patch 10 that makes this possible ...
On the other hand, it looks very interesting from 1:18 min on. Either it is a big group after all or they are NPCs ... In front seems to be Jaheira with three Flaming Fists. The left woman with the skulls and the wooden sickle and the wooden shield looks exciting. Reminds me spontaneously somehow of a Death Rites Shaman. The enemy squad starting at 1:20 min shows cloaks with a downward triangle with a skull and blue hand above it, so probably the Cult of Absolute.
This golden awakened statue looks like some kind of Golem to me, followed by an Artificer / Necromancer corpse sticker.
The city of BG looks like the mediterranean Númenor of LotR - RoP. This is how I would have imagined Calimport in Calimshan, for example. BG 1, on the other hand, I remember as a bit "rougher and grayer":
