Marvel Entertainment shared a new Avengers: Age of Ultron poster via Twitter today.

Unfortunately, The Vision’s image is still a hovering shadow in the backdrop (above the Hulk’s head).  The only previous image is above Quicksilver’s head in the concept poster here (see "'Age of Ultron' Concept Art Posters for Hawkeye & Quicksilver").  He has yet to show up in the trailers (see "New 'Avengers: Age of Ultron' Teaser").

The film releases on May 1st.
