While the TV show’s overall plot remains under wraps, it sounds like Anthony Mackie got to throw around Captain America’s shield a whole lot.
Personally, that seems like a big clue on the Sam-as-Captain America front.
That said, previously released concept art revealed that Falcon has a new suit for the Disney+ series, so it’s unclear whether he will get to don Captain America’s traditional uniform in public, or if he’ll have to fight U.S. Agent — Cap’s copycat if there ever was one — and the government to hold onto the mantle.
