At the end of The Falcon and the Winter Soldier changed the title to Captain America and the Winter Soldier but I do not think that will be the title of Captain America 4 because it could be to confusing for casual audiences since they already saw a film called Captain America: The Winter Soldier. I know everyone wanted the new title to be Captain America and the White Wolf and if Bucky Barnes actually uses the title of the White Wolf as his superhero name in Black Panther: Wakanda Forever then I think it could be the real title
