I think that is will be all Roman as I said before. However, if we find out later that this book will have 4 narrators, I am guessing that Annabeth will be the fourth as she has one POV less then everyone else in the series. If she does get the POV, then I'm pretty sure that Book 5 will have a POV for everyone, regardless of how messy people think that would be.
