Has anything regarding this been said? I think it was a pretty neat thing in previous games, day and night changing things like creatures who are present, affecting races, skills, items etc.
DoS2 was obviously built without this, but I think it has a much more important conotation in dnd.
However I am sure it is a big deal to work this through - stealth for example is based on cast shadows, so depending on how the team implemented light/shadow detection.
Based on that, I find it likely that Larian's decision on this had already been established, if not announced.
Too much work - I'd rather have content. You can go into the Underdark if you don't like sunlight
