Back in June 2019 there was some discussion regarding the LS and a lack of communication regarding content releases.
In that thread, Cordovan stated:
At this point, no one knows what is happening and when the next release will be. I see a lot of speculation that it will be by the end of this month (January 2020), but the original timeline of LS content release would have had Riders of Rohan dropping in roughly March.
I understand there are a lot of priorities out there for SSG, but I'm finding it disappointing that there has been no communication on the next release. I imagine players on these servers would really appreciate an idea about what is happening, and would prefer not to get an abrupt release notice again. Cordovan's comment seemed to suggest there is a timeline of some sort, and that this is being discussed internally. Can you give us an idea at this point of where we are at? We are all VIP/Lifetime players on these servers and as such, I think show a dedication and appreciation to this game that deserves some communication regarding legendary server status at this point.
