I feel this series deserves a topic on it's own, or did my scanning through posts just not pick it up?

The Season 3 Finale left a lot of questions unanswered and I would love to see a Season 4.

Elam "dying" too a bear as they portray but not officially dead, don't see why they would kill off an important role in the series.
Swede and Bohanan finally meet up again and now Swede is basically walking boss over him now.
Durant gets the railroad back, and it's obvious nobody wants to work for him.
The Mormon kid Bohanan basically adopted is still alive and knows what Swede did to his family, which could cause an uprising on the Mormon Fort?
Not to mention Bohanan is married to an 18 year old ( 19 year old in a month ) girl now, with a kid on the way.

So many unanswered questions really would love to see a season 4 holy moly.
