It doesn't seem like it, in fact Golden Abyss didn't have that much of an impressive writing, but that was Bend Studios. I'm sure they can do an equal script if they know what they are doing!
That's because it was a handheld game. Games for home consoles tend to be much more ambitious in every aspect. I hope whoever substitutes her do a good job but I personally wouldn't have changed what seemed to be working notably.
