Pretty much the same as above.
I am very sceptical about you, Obsidian, doing this. You haven't really done anything but build upon other companies's IPs, with mixed results.
If you make a proper oldschool RPG like Baldur's Gate or Planescape: Torment, I would be very interested and even accept a less-than-great game.
What matters a lot is partly the gameplay, but the setting is also very important. If you set it in Forgotten Realms or Planescape I'm sold - if not, I'll probably be very iffy about throwing money after it.
