I know it is a ways off, with the release of Baldur's Gate: Enhanced Edition which just came out, and following that Baldur's Gate II: Enhanced Edition. But the team's goal, ultimately, or so speculation has stated, was to be able to eventually make Baldur's Gate III. So I ask you, as the community, what do you want most from Baldur's Gate III, please, no spoilers, or at least be cryptic when talking about something in past games.
An example of some things I want:
Classes: Duskblade, Warlock, Witch
Races: Goliath (2nd edition equivalent), sub-races similar to Icewind Dale II
All the portraits and voices from Baldur's Gate I & II carried over as well as some additional ones.
Similar style of game using the infinity engine, please don't change it! 2nd edition rules still, please as well!
If the maps are large enough, the ability to ride mounts for faster travel.
More micromanaging in certain ways, but in a way that is optional. Like buying horses or carriages or even a place to stay and store your loot. Possibility of being able to set up shop and actually sell wares from your adventures, getting offers from NPCs on what they would pay for a certain piece, you can accept to decline the offer. The ability to eventually become ruler or a land (optional) and expand on the territory, we get to see visual results based on decisions, such as added buildings, NPCs, merchants, etc...
The game could use an ultimate boss battle, possibly an optional boss that is really hard, such as the Tarrasque! Which someone mentioned in a previous thread.
More NPC's from the myth and lore of The Forgotten Realms. So perhaps more true to character Drizzt and party, Elminster, Forgotten Realms classic characters, etc... Just fun easter eggs to run into when you see your favorite character from a story.
