Earlier today, the official Good Morning America Twitter account hinted at a big Avengers announcement on tomorrow’s show. That tweet, as shown below, was occupied by a clue featuring Hawkeye’s arrows.

Hours later, Robert Downey Jr. did the same thing, this time featuring a piece of the Iron Man armor in his clue.

Both tweets clearly state it’s something Avengers related, and both seem to feature bits of text, though it is difficult to make out what is spelled out as the images are cropped to hide those bits of information. So, what could this announcement be?

With Avengers: Age of Ultron set to release in less than a month, it could be an exclusive clip or some sort of contest. (Worth noting: The cast will be presenting an exclusive clip at the MTV Movie Awards on April 12th.) Or it could be something related to Civil War. The cast of Captain America: Civil War keeps referring to the film as Avengers 2.5, tomorrow’s big announcement could be the confirmation of the cast for that film. After all, Civil War is set to start filming any day now. (There is a photo that has hit the web featuring the Stark Industries logo, but as pointed out, it looks like it’s mainly for exterior shots.) Or it could be the announcement that the Russo brothers will, in fact, be directing Avengers: Infinity War Part 1 & Part 2 as the trades have already confirmed.

What do you think it could be?

Be sure to check back here tomorrow once the announcement has been made!

Now this one looks like it could say Jimmy on it. Maybe the cast will be premiering a new clip on Jimmy Kimmel Live? That seems more than probable seeing as Disney does love their corporate synergy.
