Just when we thought we couldn’t know any more about Avengers: Age of Ultron, Robert Downey Jr. teased yet another big announcement for tomorrow.

According to Downey Jr.’s Twitter account, a “big Avengers announcement” will land on tomorrow’s (April 7) episode of Good Morning America. But the announcement’s news may hit sooner for the sharp minded, as Downey Jr. offered a clue on what the annoucement might entail. Dropping the hashtag #unscramblintime, along with a partially-covered photo of what looks like Iron Man’s armor, Downey Jr. left it to fandom to discover what the announcement may be.

But, if you can’t unscramble Downey Jr.’s puzzle, there’s always tomorrow morning. In fact, Good Morning America is getting in on the puzzle-solving fun as well. The show's official Twitter account just posted a teaser tweet with what looks like a Hawkeye-centric clue (well, unless anyone else picks up a quiver of arrows in Age of Ultron).

See if you can unscramble the below clue and tune in to @GMA tomorrow for an #Avengers announcement. pic.twitter.com/BN7TtFNOZl — Good Morning America (@GMA) April 6, 2015

UPDATE:

Now late night comedian Jimmy Kimmel is even getting in on the action, posting a Captain America teaser image with instructions to tune into Good Morning America. With three teasers in the can, it now looks like the the white shapes blocking the images are characters of text. As to what they could be spelling, however, is still anyone's guess.

We're looking forward to hearing some special #Avengers news tomorrow on @GMA... pic.twitter.com/DfPUwYGGPm — Jimmy Kimmel Live (@JimmyKimmelLive) April 6, 2015

Good Morning America airs at 7:00 a.m. on ABC.
