I expected Minthara to be completing the group of evil companions. I assume that Minsc will not show up in chapter 1. If the assumption of having to part ways with all but 3 companions after chapter 1 proves to be correct that would indicate the possibility to grow the group again once a new camp in the new area has been found.
I sometimes use thought experiments. I don't necessarily believe in every idea I post for discussion on this forum
