The game has officially been shelved. From Reddit:
We would like to provide an update on Legends in regard to new content. Our previous roadmap indicated we would be releasing one more set this year. We decided to put any new content development or releases on hold for the foreseeable future. This decision will not in any way affect the release and development of GAEA’s Asia-specific version of Legends, which is operated separately, but will inform our decisions on content and feature development going forward.
Until then, you can still download and play Legends on all existing platforms and compete online as well as in the single-player modes. We will also continue to support the game with monthly reward cards and regular in-game events. New expansions and other future content, however, are no longer under active development. We will continue to provide ongoing maintenance support.
This is not surprising. The last time The Elder Scrolls: Legends was in the news was when it showed up at E3 as part of Bethesda’s terrible conference, and both before and after that it failed to get any notoriety or publicity. It just didn’t grab people, and Bethesda is probably better of using the manpower behind Legends on another project, like thinking up new ways to ruin Fallout 76.
Still, a lot of people appeared to have liked it, so, sad for them.
