With very little known about Kingdom Hearts 4 right now, there is still a lot of room for speculation based on the bits of information and teasers available. Although what has been shown about Kingdom Hearts 4 has mainly focused on Sora awakening in the realistic world of Quadratum, fans have been theorizing that the series will finally introduce a Star Wars world in this entry. However, the introduction of a Star Wars world brings with it a new problem that Kingdom Hearts 4 will have to handle very carefully given the hype around this potential crossover.
