Marvel's The Avengers is proving to be the phenomenon of the summer, reaching over $1 billion in ticket sales after only 19 days on screen. In the midst of all the excitement, Marvel President Kevin Feige has revealed that two unnamed Marvel films are on the verge of being announced for production in the very near future. Of course, he didn't give any hints about which two superhero franchises these could be.

"In a week and a half we start filming Iron Man 3...By the end of the summer we'll be working on the next Thor film, early next year the next Captain America film. Those are the three that we've announced so far, but we've got two beyond that we haven't announced yet that we're working on."

Speculation is already running rampant about which two films he is referring two. Ant-Man is unlikely, as director Edgar Wright already has his 2013-2014 slate full with The World's End and The Night Stalker. So that leaves the films we already known to be in the pipeline, which include Black Panther, Doctor Strange, The Guardians of the Galaxy, and possibly Iron Fist. Though, both upcoming titles may also be movies we've not yet heard batted about.

What do you hope the next two as-yet-unnamed Marvel superhero films will be? We're betting on a third stand-alone Hulk reboot ourselves.
