"They may wait until 2014 until they release the next Cap. Marvel has a lot of balls in the air, they aren’t going to cannibalize their films.” And it could be very expensive for Marvel if Cap shows up in a non-Cap movie. “Out of those six films, if I pop up in one of those [other films], it counts as part of the deal. So if they needed me in a third Cap, and I say, ‘Fuck you, give me $30 million,’ well…they want to avoid that."
Previously it was announced Marvel Studios had two films set for 2014 the first one May 16th and the second June 27th. I assumed that the sequel would be one of these dates, it sounds like all but confirmation with Evans' statement. On the other hand Marvel has yet to announce dates for Ant-Man, Doctor Strange, Black Widow, Nick Fury, Iron Fist and Black Panther. They could wait to test the waters with new characters before rolling out a sequel.
