In 2015, the British Open returns to St. Andrews. In 2016, the U.S. Open returns to Oakmont.
WGT already has both of these courses, so perhaps the courses for the Women's Opens will be used instead, or the PGA Championship courses.
However, I would like to see some sort of a poll held to decide which course is made in each of those years - presuming of course that WGT is still going at two courses a year and that the British Open courses continue to be produced (another matter entirely).
Obviously 2015 and 2016 are a long way off, but with the length of time it takes WGT to produce a course, plans have to be made early.
Jack.
