Very little is known plotwise about Captain America's sequel, Captain America: The Winter Soldier.
But we do know that Steve Rogers will be interacting with a handful of classic Captain America characters, such as Bucky Barnes and the Falcon, played by Anthony Mackie. In a recent interview with AICN, Mackie revealed a few important details about the modern day version of this character. And oh yeah, he's gonna fly. http://feeds.gawker.com/~r/io9/full/~3/B9jnXhsKWmM/anthony-mackie-reveals-marvels-high+flying-plans-for-the-falcon-in-captain-america-2
