It's not happening.
Also, it's one of those issues where throwing a bunch of money at it doesn't really help. As much as I would like to see it, they have other priorities, and it's not happening for DOS II. From Swen himeself:
So on the day/night cycle (Swen here again) - what we're trying to do at the narrative & scripting level is really complicated and my head is too small to even contemplate adding yet another extra dimension of complexity to that. The impact of your origins combined with at higher level of freedom than the already insane amount D:OS gave together with the option of multiplayer = complex development, and until we tame all of that, we won't add an extra layer. Perhaps for a next game, but definitely not for this one.
