Yeah because the latest patch is the last patch they are making for Brink and will never update the game ever again.
The first two you list aren’t as simple as people seem to think, they just cant turn of button on and have it magically work. There are fundamental differences between Brink’s iteration of idtech4 from all others that unfortunately meant some features don’t quite work properly yet. They most likely haven’t said anything as they don’t know if they can or can’t get them working or not.
