As I already said weeks ago, I'd be more or less fine with whatever they pick, if well executed, and quite frankly I doubt any arguing among users is going to change whatever Larian most likely already decided and set in stone a couple of years ago.
That said, I have to say I tend to resent the ongoing implication among several users that "If you are an old school BG fan you'll prefer RTWP" (typically followed by "if you prefer turn-based you are probably just a recent Larian fan").
I'm 41, I played all these games when they launched and I was even an "adult" already back then, I still hold BG2 pretty damn close to the top spot of best RPG ever made (at very least in the top 3 for me, for the plurality of things that it did right) and I STILL think the real-time part of its combat used to be one of its weakest elements and something resembling a hybrid between DOS or Temple of Elemental Evil would make for a better game, with better battles, given some proper encounter design.
Party control in Baldur's Gate 3 is a complete mess that begs to be addressed. SAY NO TO THE TOILET CHAIN
