borntobesting: If you mean the future courses in the USGA championship Zone all it shows is the year no specific date. And actually if that is what you are referring to that is the U.S. Open courses for the next few years. It doesn't mean that those are the courses we will get. Last year we got Oakmont which was not the U.S. open course but the ladies open course , If there is a page that does show a specific date I can't find it.
Well, they are all listed under the rubric "Future Courses" with the year when the US Open will be played there. It certainly implies that each course will be made available during the given year. Granted, anything could happen between, say, now and 2019.
