According to Vander the next update will be way shorter than the last one (
which was the largest since release at 1815 renders). U30 is currently at 230 renders, so I'd guess early to mid February.
That's great, because I just binged through a first play, and I desperately want more. Was thoroughly disappointed when I hit the end of current content (for all the right/good reasons... this game quickly became a must play religiously for me)
