Der har aldrig været de store grænser for hvilke Disney-eventyr Kingdom Hearts-serien har flettet ind i sin historie, og derfor kommer det heller som ikke en overraskelse at spillets skaber, Tetsuya Normura, gerne så både Star Wars og Marvel-universet som en del af det kommende Kingdom Hearts III.
I et interview med Finaland fortæller Normura om ideerne, men siger samtidigt er det ikke er så ligetil:
"...We've been talking about Star Wars itself since it became Disney's content recently. When I eared the news I was like "Wow ! Wow !". Yeah obviously it's gonna be great if we could add it, but like I said there are a lot of restrictions and rules by Disney so we don't know what's gonna happen but yeah, we'll see."
