MARVEL The Avengers 2: Age Of Ultron Movie Poster by ProfessorAdagio
This is not official, I made it myself.
The official San Diego Comic Con Teaser Trailer for Avengers 2 shows Iron Man's Helmet being transformed into Ultron, so we know it involves Iron Man's armour in some way.
And a stand alone Ant Man movie from Marvel is also in the works, so that will be a separate thing with Hank Pym.
Marvel movies have a way of being different from the Comics.
