Milch wrote essays about the show and characters for a book that came out after the show ended. If I remember correctly, he says that he had lots of ideas for stories for some characters, none for others and no master plan for the series despite what he had said previously (and given the quality of work that they were putting out, I don't see a problem with 'making it up as they go along'). Long story short, there was no definite plan or number of seasons that the show was set to run or grand conclusion that he was going towards. That being said, I'm sure if they had done the telemovies or they knew that S3 was the last one, there would have been much more final endings for the characters than actually happened.
I borrowed the book (entitled "Deadwood: Stories Of The Black Hills") from a friend but I always meant to pick it up. I'd definitely recommend it to any big fan of the show.
