Possible return of rest of Organization?

Is there a possible return of the rest of the members? I mean, we already know that Xemans,Braig,Dillin,Even,Eluas,Inezo,Lea,and Ïsa are coming back due to dream drop distance. But what about Demyx,Marluxia and Larxene? I think they could due to two lines. Kingdom Hearts II, by Demyx:".....oh, we do too have hearts...." DDD: well I don't remember who said it, it was either Young Xehanort or Braig. But they said that they had hearts to begin with((I think)) that they fooled the others too get vessels for Xehanort's heart-The Thirteen Seekers of Darkness. I think that we'll see Demy,Marly, and Larxy and the others once again. Weather or not they remember Sora or not, I don't know. And if they can be on your team, can be determined by a mini game. Like for Demyx, you could do a timing mini-game((am I the only one who enjoyed that in kh2?)).
