Sven all but confirmed that they are making BG3 for fans of DOS2. Not fans of the original series, not fans of tabletop DnD, but for their fans whom have already purchased their previous games.
He also confirmed they are working on improving combat and other mechanics based on feedback. Since we don't yet know which feedback - let's not take one comment out of the context of the entire interview, let them work and see what happens, hmm?
