We have some estimations internally, sure. But they are far from set in stone (many moving parts that depend on how well the closed tests go) so I would hesitate to share them with you. We are excited about it too and hope to release them to you in the near future.
You guys need to figure out a multiplayer roadmap with timeline estimates. The majority of these hate threads revolve around a lack of transparency. For a community that has shown incredible support the past 12 plus years we sure do get the corporate response quite often.
Will private servers be released with the full game?
Will they be open to everyone?
When is the estimated game launch? Oct 15th?
Planned multiplayer additions and their estimated timeline/progress on these additions?
I would recommend you as a dev team do a AMA style stream on youtube/twitch. Might relieve some stress the community has. Hope this helps.
