My biggest concerns and fears upon learning of that article is that a different studio will pick up the torch of Baldurs Gate 3's legacy and then do it dirty just to make money out of it, I really hope WotC will be very careful with this IP, its burning so hot right now that it just feeds on my fears that some money siloed studio would not do it the justice in long terms, hopefully Baldurs Gate 3 will remain untainted in the next 5 to 10 years.
It cant really be worse than BG3 though. BG3 has an atrociously bad story and bland characters and is only held aloft by brand name and shippers.
A studio that knows how to write stories could also deliver a much better BG4 or DLC.
Just imagine what Obsidian could do when you consider hiw they managed to upgrade games with DLCs (Mask of the Betrayer, New Vegas).
