A new interview at Ten Ton Hammer, along with today's live stream Q&A, has given us an idea of the remaining development timeline. You can read the article here:https://www.tentonhammer.com/articles/crowfall-interview-war-of-the-gods-marks-a-major-milestone
and watch the video here:https://www.twitch.tv/videos/486637480##
The next update (5.110) will be a huge one, and is slated for early 2020. In the Q&A, Todd said maybe January, but more likely February, with some testing of individual things prior to that on the TEST server. Once that update is live, they will be in polish and balance mode, and after that, launch.
Not only does the next update include the Dregs (guild vs guild pvp), but it also adds more layers to the pvp strategy game, while allowing guilds to build their own cities. Previously, city building was only in Eternal Kingdoms (personal worlds used as market and/or social hubs). The in-campaign city building will be even a step or two beyond that, as we will be able to place specific buildings that provide different benefits. I highly recommend watching the video for all the details (starts at 32 minutes).
We don't know how much balancing and polishing will be needed or how long that will take, but the finish line is definitely in sight.
