At this point, it feels almost inevitable that Kingdom Hearts 4 will feature the Star Wars franchise in some shape or form. Now that Star Wars is one of the biggest parts of Disney, it's nearly impossible for Kingdom Hearts 4 to be made without including one of the most iconic pieces of pop culture history. There is a lot of speculation about what Kingdom Hearts 4 will entail, but an appearance from the likes of Luke Skywalker or Han Solo seems to be set in the stars.
