Square Enix, updated everything, weapons, that the villians have are different colors, and so forth, don't worry about it. It's just like how Japanese got a different view, when Xigbar is trying to snipe you, and you have to dodge it.
They get a little more of a battle scene, and we get the short version of it. It's kinda gay, but then again, I heard it was a spoiler, but whatever.
