Marvel Comics has released a new teaser containing two puzzle pieces and a question: "Who is Mosaic?"
Given Brian Michael Bendis's recent statement confirming a new solo Jessica Jones series was in the works, and thie image's easy comparison to David Mack's covers for the original Alias series, this could easily be the first official sign of that project.
Marvel confirms, however, that Stuart Immonen is the artist. Immonen is currently working on the creator-owned Icon series Empress, and has no current Marvel projects announced.
Newsarama will have more as it develops.
