I don't know if they will do it, but it occurs to me it would be nice if they redid some of the voice overs since in some cases the actors had lines but no context to go with them.
You mean while traveling around towns and stuff? This would work out great; they have done it in recent games and it blends with the story.
That as well. Mostly I mean in some places where certain characters (mostly Tidus) say things that don't sound quite right given the context. The reason for it being that the VA didn't know the context in which they were supposed to be working.
