Good sales means more RPG fodder in the future and maybe a D:OS3.
I wouldn't say that good sales [of BG3] means maybe a D:OS3. If anything, relatively disappointing sales of BG3 would be more likely to give us a DOS3, as Larian would decide that making D&D games isn't profitable and go back to their golden goose. Assuming of course that sales of BG3 are good enough that Larian doesn't go bankrupt, which is already true I think.
Whereas if BG3 sells 10M+ copies, then I doubt we'll see another DOS game for a while.
