There is an image of Provenance in the "New Version Update in the Works" banner on the Playonline page. This is the article about the March version update, so unless they're trolling us, it's something coming in March, and most likely Voidwatch related based on the text of the summary (the summary highlights legion and Voidwatch and the other image in the banner is definitely Legion).
