Birth by Sleep an od view?

I think that the place where final mix+ secret ending takes place is in fact Sunsett hill. Just a theory, and nothing to prove it with exept that i just felt 3 things the first time i saw the video.
That the old guy was in fact Ansem the Wise,
That the person they see in the first part is some one different from Master Xhenahort, more like someone from Orginization XIII,
and that when u see the Mountain of rock created by MX, its really Sunset Hill(u'll understand it better if u watch the part with mickey)
just a thought.....comment please...

 

Don't they fight in the crossroads which I'm starting to think is the same crossroads from kh:com which is near castle oblivion.

 

well looking at the video i really don't think it's any world we know but then again i maybe wrong

 

It takes place at a crossroad..
preferably the one close to Castle Oblivion like Darkblade said
