in recent interview sven has mentioned they are taking risk making it differently. don't expect it to be a bg2 clone according to him and they are unsure if the fans will like it or not. he also specifically mentioned in his earlier career, publishers don't like turn-based and their success with DOS2.

my guessed for no. of players would be 4. those are the best and safest number to make RPGs for all platforms. 3 are too few and 4 has appeared in many RPGs that were also available for consoles and handhelds. even pillars of eternity 2 reduced party characters to 5. they knew they wanted it 4 but cant as 5 even gotten huge backlash. i honestly think BG3 will not have 6 party characters. It will be 4 as that is Larian magic number. It could also possibly be 5 but i seriously doubt it.
