Well I actually know the answer but I think it kinda sucks.
Let's face it:
First 2 games with expansions were all about the Bhaal Spawn. And we know that story is over(it is over right?). So it is not a sequel based on the story.
We don't know(but you can bet on it) that this game will not be using the infinity engine, so it's no a sequel based on that.
Heck this game won't even be using the same version of AD&D rule set. 3.5 instead of 2.
The only reason I see this being a BG game is because of this supposed appearance of ancestors of some of the characters from BG.
But mostly I think they are keeping the name to make a load of money, because, as I am sure many will agree, most gamers are more likely to buy a sequel to one of the best RPGs ever rather then a brand RPG.
