I think most of people here tend to forget that Baldur's RTwP was actually very flexible. You could adjust the game to pause automatically after selected actions, wchich Led to making it Turn Based if you needed/wanted...
So i think the discussion about wchich system is better makes no sense as Baldur's system could be what you want - real time, Turn Based, or something in beetween. It was up to you how you want to play.
As many people have said here, Larian is not making TB because it's better, they are making it because it's easier for them...
I think it's a pitty when they are creating a game with such a Legacy as BG, you should realy try to make it feel like a part of This Legacy (i don't mean 2d) and not only using it as a settinga.
Otherwise it could be named Forgoten Realms : Divinity Lost
