Kevin Feige confirmed that it's "primarily" a period piece that takes place during WWII. He said they went and looked at Raiders of the Lost Ark, which he says he "didn't know" was a period piece when he was watching it. They want to make Captain America with the "same level of fun" as that. And in regards to director Joe Johnston, he said that this would be a little bit of The Rocketeer, lots of October Sky, and a little bit of the ship designs that Johnston did for Star Wars, alluding to how this is the perfect movie for him to direct. "It's the movie his entire career has been leading towards."

One reveal Feige did make is that Cap's sidekick Bucky would indeed be in Captain America. When asked by Boucher if he'll appear, Feige said "it's a safe bet" that he'd be in the movie "in some capacity." Moving into The Avengers, he was asked if Cap would be involved right from the get go: "Yes." Feige initially said that they talked about making The Avengers animated because it was so big and had so many characters (refer to this old article). But then he said "why don't we wait" until they introduce the characters in their own movies and then have them all come together in a "surprise" manner in a big Avengers movie.

What was so great about listening to Kevin Feige talk is that I could tell he's a fan and knows how to do things right. "Having an idea is one thing, bringing an idea to life is another," he said at one point. His recurring message was that they only do things if they can do them right. As for other projects on Marvel's slate, he did mention early on that Edgar Wright is currently finishing up another draft of Ant-Man for them to look at after he finishes Scott Pilgrim. Lastly, Feige also said that they'll be announcing another new movie for 2012 within the next few months. It's probably not Ant-Man, so what else could it be?
