they decided to change it throughout the years of development

Things change over the years. Some of the scene are taken out and most of them were just relocated.

 

Here is a video showing scenes from some of the old BBS trailer and what it looked like in the final product:

 

And the Days HP bar layout, I guess they just wanted to change it. If I remember correctly so did they changed it 3 times.

I didn't realize they took out some cutscenes, but meh bbs turned out good i muct say

Like they've said, it has changed since the first version of the game, much has been modified.

That's a noob move for not knowing the game can change until the final product.

Yeah, those were either removed or relocated, like when it shows Terra about to fight Xehanort in the sandstorm, that was moved to up on the earth pillar and Vanitas was added to it. And then the part where he is holding Ventus in the gorge in Radiant Garden was moved to Land of Departure. The part where Ventus is on Destiny Islands was edited and put in the Keyblade Graveyard.

I really would've liked to see the cutscene of Ventus saying "Erase me" but...no.

Some of the scenes were taken out, while others were taken in a different place

I really would've liked to see the cutscene of Ventus saying "Erase me" but...no.

 

Ventus said "Erase me" in BBS, but it was in Keyblade Graveyard instead of Destiny Islands

Yeah, but it would've been more better on destiny islands. I don't know why. It just would've.
