In April 2022, RGG expects to release Dominion: Seaside (Second Edition), with this expansion for either of the Dominion standalone titles containing nine new types of Kingdom cards; as happened with the new cards for the previous second editions, these cards will be released on their own as an update pack for those who own the first edition of Dominion: Seaside. A few cards will receive minor errata, but these will not appear in the update pack.
Rio Grande Games pass along this announcement from Vaccarino for this edition:
So far, we expect Seaside 2E in people's hands in April (in English; other languages are still in the works, but German, Japanese, and Dutch will probably not be far behind). We will update everyone if the date changes or becomes more pinned down. And we expect to do previews just before the release.
So until then, you do at least get to speculate: what cards are leaving?
As for other Rio Grande releases, all of these titles arrived at its warehouse in mid-to-late January 2022 and will head out to distributors and retailers over the coming weeks:
