If your talking about the new co-op function that is being implemented into KH2, than yes there will be more. Nomura has even said so himself in one of the interviews about the co-op's functionality. According to Nomura, the co-op function is at the very heart of the game in terms of the combat system just like the triangle attack and drive abilities that you will also be able to utilize throughout the entire game. So in short you will be able to do more cooporative attacks with characters like Beast, Auron, and any of the other characters that will join your party.
