I doubt Larian will make another D&D game. They have no love for the limitations of the D&D system and their own IP to maintain. Doing BG3 was more a prestige issue than a endorsement of D&D.
They can cycle both ips to a oud burnout of either
They could. But that also depends on what WotC wants who are notoriously bad at managing their digital IP and also rather greedy. And now after BG3 is made the big prestige reason to do it is gone unless they make something like Planescape 2. They could also do it like Owlcat and switch IPs. Rifts would be right up their style and no one cares about Rifts rules. Only the owner is a tad overprotective of his IP.
