Being a prequel many NPC's could appear... any elf or drow for example... a young Gorion could be a nice choice... Anyway, as some of you have said, it would be better a game with more new characters.
I always miss to visit known places when I play a BG game. It would be really cool to revisit Nashkell or even Beregost. It doesn't need to be exactly the same... Or even a place taken from the NWN adventures! Wouldn't you like to walk through the streets of Neverwinter with your BG party?
