Considering that WotC recently decided that Half-Orcs are not politically correct I am not sure if they will be added.
Those are being removed for One DnD. BG3 is based on DND5e and we already have the confirmation that all PHB races are in.
Doesnt change that Half-* = bad is the current stance of WotC they are now enforcing. The portrayal of drow (Lolthsworn) in BG3 is also rather new and was only created by WotC while BG3 was already under development.
