The next King's Bounty game is apparently trying out 3rd person exploring a'la Withcer etc joined with turn based tactical combat. That's a game from a different genre sure, but it looks like it could work well for that and a new take on that series.
I can say with absolute certainty that they have 3rd Person exploration as well. They use face-scanning which would be utterly pointless in anything but a 3rd Person/1st person camera. Anyone who still believes BG3 will be completely isometric is simply ignoring facts
