I am not casting aspersions on anyone by saying this, but I would be worried about committing myself to things happening in a session, if I titled them based on what I thought would happen. It's easy for me to dump or back-burner something, working without titles or other expectations, and it's pretty clear that neither @Blue nor @el-remmen are forcing anything--this is just about my own shrinkology.
And just to be extra clear, the names are based on what is most likely going to happen or was already clearly established would happen. For example, in the list immediately above, the party decided at the end of session #1 they'd be traveling south. So the next session was easily entitled, "On the Road South." That is not a spoiler or a so-called railroad.
