Aside from the upcoming release of Kingdom Hearts: Birth by Sleep, we don’t know much about what Square-Enix has in store for the series next. While people might assume Kingdom Hearts 3 would be on the way sometime soon, Tetsuya Nomura says something else might be rising.
When Nomura was asked if the series would continue after Kingdom hearts 3 he said ““Kingdom Hearts is Sora’s story, but the series in development now is also another character’s story. So to speak, that character is the focus of this series.”
Beyond this Nomura wouldn’t say much more, but he did say that there would be another title that would wrap these two series together.
