I was mostly correct on my prediction yesterday. It turns out that there is one more chapter, but it seems like it will be dominated by combat. Essentially, the last boss is too enormous to be contained at the end of one chapter, and needs his own to really flex his muscles. Also, I am glad that I am actually given the choice of which girl I want to be with at the end of the game, for a little while, I thought that the game might force whichever character I had the strongest relationship with, but that is not the case. It should make getting many of the character endings much easier, and obviously allows me to get with the character that I want to, which in my case was not the one at the top of the relationship chart.
