About to start Exodus

I recently finished 2033 Redux (7.7 hours) and Last Light Redux (10.9 hours). Both with good endings (yay). How much time should I plan for Exodus. I heard it's a lot longer due to open world segments. And so I'm curious to what to expect time wise since I will have a busy few weeks. So I might tackle it at a later time if it's too long ^^
