Probably won't reuse, as the setting for this particular one is a bit...odd and removed from the rest of the series (though it will tie in here and there).
But no, I'm sure everyone would have liked more battlesex stuff, and there will be a fair bit of it with the wolves, but "there's only one enemy with palette swaps" was a recurring direct complaint for both games, which is somewhat understandable. The client dogs were an attempt to stem this in GT, but then they ended up in their own area and not really appearing in combat. The rats ALSO ended up with their own area, but you will definitely be fighting them!
