Kingdom Hearts creator Tetsuya Nomura has teased a "smartphone development" for the series.
Talking to Japanese gaming magazine Famitsu, Nomura was primarily discussing forthcoming announcements for Kingdom Hearts III, which is heading to PS4 and Xbox One.
However, he added the following at the end of that discussion:
"One of those announcements will be about a smartphone development for the series, which I believe we’ll announce in the near future."
Whether this will be a companion app for Kingdom Hearts III, or an original Kingdom Hearts title for iOS and Android, or something else, we don't know.
But it's enough to get us eager to find out. The announcement will be made during D23 Expo 2015 which, unfortunately, isn't due until August 14-16th.Siliconera
