According to a voice actor, yes.
After the announcement at E3 last year, Kingdom Hearts 3 finally gets talked about. On Twitter, the voice actor Gillbert Gottfried, historical voice of the parrot Iago, has announced that he is at work in a new chapter of the Kingdom Hearts series:
"Iago the Parrot squawks again for the upcoming Kingdom Hearts video game"
We will then see the return of the world of Agrabah in the new chapter? However, it could also be the collection Kingdom Hearts 2.5 HD Remix as in the future remastered version of Re: Coded there may be a need to remake the voice of the parrot.
