I went back and checked out the old CAD photo of Battroid Mode from head-on. I know things can change between the CAD and implementation but all of the proportions look exactly the same. The only thing different is that, while the very bottom of the chin is covered, it appears the chest piece on the CAD sits lower then in these photos. I'm wondering if this prototype isn't quite sitting correct. It doesn't appear to be in fighter mode either. But I'm willing to bet that chest piece isn't set quite where it should be, which should make a least a small difference.
