2002, a press release announced a list of the English voice actors. The list included Haley Joel Osment, David Gallagher, and Hayden Panettiere as the three new characters introduced into the game. It was also announced that many of the Disney characters would be voiced by the official voice actors from their respective Disney films. A secret trailer in the first Kingdom Hearts and Kingdom Hearts Final Mix hinted at the possibility of a sequel. Rumors for a sequel on the PlayStation 2 were spurred in Japan when a Japanese video game site, Quiter, stated that "an internal (and anonymous) source at Square Japan" confirmed that development of Kingdom Hearts II had begun.

The rereleases of the main series games had the term "Final Mix" added after the title, while Kingdom Hearts: Chain of Memories and Kingdom Hearts Coded were re-released as Kingdom Hearts Re:Chain of Memories and Kingdom Hearts Re:coded and released on the PlayStation 2 and Nintendo DS, respectively, with 3D graphics, voice overs during some cutscenes, and new game content.
