The comment about the camera perspective is indeed interesting.
I don't like speculating too much, especially not when we currently don't know anything about the game, but I'm really curious to see what he means by his statements. If I were to take a guess I'd say the most reasonable guess would be a tactical / third-person hybrid like in Dragon Age: Origins. I've seen some people speculate that BG3 will be a full-blown third-person ARPG, but personally I find this idea a bit too far-fetched.
