MTV caught up with director Jon Favreau, who revealed that Iron Man 3 will really be a sequel to future Marvel adaptations Thor, Captain America: The First Avenger and The Avengers. Here's an excerpt from the article:

"In theory, Iron Man 3 is going to be a sequel or continuation of Thor, Hulk, Captain America and The Avengers. This whole world... I have no idea what it is. I don't think they do either, from conversations I've had with those guys."

Jon Favreau also said he wasn't sure how Iron Man 3 would shape up, although it will likely depend on those previously-mentioned movies:

"Honestly, right now Captain America and Thor are their big priorities, and you learn things by shooting and making movies. The script is one thing, but when you actually see what you land on at the editing room - especially with Marvel where they film, cut, film some more and shape the film - you really learn as you go."

We reported earlier today that location scouting was already under way for Iron Man 3 in Troy, New York. We also reported in October that Iron Man 3 already has a release date set for May 3, 2013.
