Like the subject line says: unconfirmed reports of the plot for Captain America 3 are behind the cut.
Variety reports Cap 3 will be a Civil War plotline.
Robert Downey Jr. is on the verge of signing on to “Captain America 3,” a move that would bring the Civil War storyline from Marvel’s comicbooks to the bigscreen and trigger the start of a new phase of movies from Marvel Studios.

The deal is significant for the Marvel cinematic universe considering the plot will pit Stark against Captain America’s alter-ego Steve Rogers, played by Chris Evans, as they feud over the Superhero Registration Act, which forces anyone with superhuman abilities to reveal their identities to the U.S. government and agree to act as a police force for the authorities.
Stark supports the program, but Rogers does not, saying it threatens civil liberties, causing sides to be taken and Rogers, among others, to go on the run to avoid arrest.
I mean, I guess it makes more sense post-collapse-of-SHIELD and with new powers on the scene for Avengers: Age of Ultron, but still (1) that's not enough secret superheroes for this to make sense and (2) entirely out of character for MCU!Tony!
I just, ugh. This is what I get for procrastinating by opening Twitter.
