For Larian game specifically? I think the most interesting thing they have done in D:OS has been the coop. D:OS2 and BG3 have been their attempts to introduce more traditional RPG elements (coherent story, companions) into D:OS coop centric design, but I feel those two are ever in conflict. So what I would most be interested is to see is for Larian to pick a line, and try to evolve coop design that they pioneered in D:OS1.
Or they could drop coop and create singleplayer first experience - but that wouldn't be evolving. That just would be doing what other RPG developers are doing.
While I am not exactly for AI writing dialogue for RPGs - I would rather see RPGs writing get better, not worse - Arcanum back in a day did
procedural dialogue for NPCs that provided robust reactivity to our character. That is something that I think games tend to do poorly. Sure, they will script special dialogue here and there, but for the part we are treated the same. I think there is potential there to be mined - imagine if shopkeepers and minor NPCs in Baldur's Gate could respond to players in a more reactive way, than having a pre-written bark. Or if dialogue could take into account systemic reputation and such.
Still, with full VO production that runs into another problem, as BG3 definitely wouldn't be better if stilted AI generated dialogue was added. If anything it is the human touch that makes the game appealing.
