Kingdom Hearts II I just realized something about the cutscenes

So,the scene after we beat Roxas is 358/2 days and the cutscene after we beat xemnas is birth by sleep,Kh2fm is getting us ready for upcoming KH games

 

he meens that in kh2 fm after those battles there was a cutscean relevent to the two games he mentioned in extension after defeating roxas there is a cutscean that refers to 358/2 days ant the secret ending had to do with birth by sleep get it?

 

Well, also, the best one in my opinion was the one where Xemnas walked down that long set of spiral stairs and went through this laboratory area. At the end was something similar to a throne room with Aqua's armor on it. and Xemnas said, "It's been a long time, my friend." I have a strong belief to think, even tho this is supposed to go in the upcoming games thead, Aqua and Xion have some sort of a connection with each other...but what could it be...?
