Update: Looks like the u3music Twitter account is stepping back from the previous statement: 

I apologize for what I said. I was little confused when asked whether we would be involved in Kingdom Hearts III. As of now it's undecided.

Original Story:

Kingdom Hearts III wouldn't feel right without a theme song by Japanese pop star Hikaru Utada, would it? Thankfully we now have confirmation of what was otherwise simply expected, since the singer's father, Teruzane Utada, gave a simple affirmative reply to a fan on Twitter.

Yes. teruzane RT @daodlionheart @utadahikaru are you involved in Kingdom Hearts 3 theme song?

Hikaru Utada's previous themes for Kingdom Hearts and Kingdom Hearts II were "Simple and Clean" and "Sanctuary," respectively.
