Tony Stark may have pulled the ultimate sacrifice play in Avengers: Endgame, but if Spider-Man: Far From Home is any indication, he'll continue to cast a huge shadow over the Marvel Cinematic Universe for a long time yet. Although there's been constant speculation that Robert Downey Jr. could be tempted to return in one form or another, as the franchise's biggest name and most popular character, there's little chance that any and all references to Iron Man will suddenly be dropped now that he's out of the picture for the time being.
