Kingdom Hearts II More b/w KH & FM+

So far, I haven't seen any one put on this

Since I am replaying KH (I) at the moment and I have just found out something might be interesting for speculation of new secrete ending in KHIIFM+. At the first arrival of Deep Jungle, do anyone remember that you need to find 6 Slides in the Camp at the very beginning. After finding them, they are displayed on the wall and the very first one is a picture of a castle that really looks like the one in the new secrete ending. Also, Sora says something like that the castle is very familiar to him though he hasn't seen it before.

And I think I am right to say that in KH (I) Sora never sees any castle like that. And not until KH (II) he sees the Disney Castle.

Just at the same time, something pop up in my mind about what Nomura said. That completely new characters in the new game (the one no under the title "Kingdome Hearts" ) and Sora might be needed in that game as well as Sora is definitely needed in the last one.
Can I say that something might be hinding there????

If I make any mistakes, plz correct

 

Im pretty sure that castle was Hollow bastion (before it got all corrupted) and it was because kairi rememberd it and since her heart was in soras.

 

Yeah, it was Hollow Bastion in that picture.
