"Will there be more content coming for BG3?" We know what we are doing next, and we can't talk about it but probably not any additional content for BG3.
This is not at all surprising and exactly as I anticipated: no content DLCs/expansions for BG3, and also no BG4. I am certain both Larian and WotC see BG3 as a complete game, and also the BG franchise as being complete and done. As for a completely new game using DnD, that is a possibility, but ...:
1) I think any discussions on such a project between Larian and WotC will be fraught with difficulties because if I had to guess, for all the happy-talk about WotC being happy with how BG3 has turned out, I believe WotC is not happy with what is their share of the profits from BG3. WotC is one of the worst money-grubber corporations out there, and especially in recent months have clearly shown their true colors on the subject of how money-hungry they are. So for any future DnD video game project, they will surely insist on a contract in which they get a much bigger cut of the profits, much bigger than what is standard in the industry. So it will all depend on if Larian will be cool with that, which I somehow doubt.
2) Larian themselves, and especially Swen, I feel, are probably of the mind that they have gotten all they can get out of making a DnD game with BG3, and from a creative standpoint are likely to want to go try something entirely different next. I would even go so far as to suggest they won't want to do another fantasy-genre game, and may instead opt for something in the sci-fi or post-apoc or cyberpunk genres.
