KOTOR2 could well be as much of a sequel as BG3 would have been. Setting's the same, and from some tie-ins to KOTOR to a direct relevance, but could for all we know have very different characters, stories, even gameplay, and I see this as more likely than a direct sequel if Obsidian is making it. In which case it would be a good idea, to at least boost sales and get the company running.
