Hot on the heels of yesterday's Avengers: Age of Ultron poster reveal comes the first character poster from the highly anticipated sequel. Robert Downey Jr. unveiled an Iron Man poster through his Twitter account … and teased a "big announcement" in eight days.

Hmmm, what could this big announcement be? If it's something directly in Downey's sphere of influence, it could be a new Age of Ultron trailer or some big Captain America: Civil War news. Don't count on an Iron Man 4 announcement. The schedule for the Marvel Cinematic Universe is already pretty packed.

If Downey is teasing something else from the Marvel Cinematic Universe, perhaps we're on the verge of some Spider-Man news?
