"We've reached an agreement, but I still can't say anything. I plan to give new information at the Kingdom Hearts Fan Event that will be held on the 3rd of November."
When asked about new worlds within the game Nomura had this to say.
"I can't speak in detail, but apart from Olympus Coliseum, nearly all the worlds are new."
In regards to the battle system in Kingdom Hearts 3 Nomura confirmed that the battle system will a return to the original series rather than the deck commands found in Kingdom Hearts: Birth By Sleep.
"The battle gameplay returns to commands such as 'attack' and 'magic' rather than deck commands. I thought that king of gameplay styles had the royal right to be used in a numbered Kingdom Hearts title."
The time is soon coming where we may know the release window for Kingdom Hearts III.
