I prefer Turn based games over Real Time, but Baldur’s Gate wouldn’t be Baldur’s Gate without Real Time w/ Pause.
News flash it's not really going to be Baldur's Gate in the way you mean it, no matter what the combat system. Ignore the name of the game, and look at the stuff they said.
Will they be making it Commodore 64 compatible?
That isn't stuff that they've said, at least so far.
Both (thus why I voted Other).
Pillars of Eternity 2 made it so that when you start the game, you can choose action, or turn-based. It works -phenomenally- with both. This should definitely be the direction so that all preferences can be enjoyed.
Barring that, I definitely agree with keeping it turn-based; as others have said, at Larian, they are masters of Turn-Based.
