Since its first release in 2002, the Kingdom Hearts franchise has released more spin-offs than you can shake a stick at. Importantly, almost off of those spin-offs include plot details that are key to the series' overarching story. A recent rumor claims that Kingdom Hearts might be expanding even further. While fans are patiently waiting for Kingdom Hearts 4 to launch, it seems that there's renewed interest in a Kingdom Hearts TV series or film adaptation. Details are currently scarce, but this new leak has fans hoping that something will finally happen this time.
