There have been many wish lists compiled of what courses we all want. I'm not sure it is realistic for WGT to go all the way to Australia to film a course but i am hoping that they will add a few courses played by the US PGA tour.
We know we will get the US Open and British Open courses in the future at the rate of 2 per year and you can look at their sites and see which courses these are. Some of the great tracts in the US, like Winged Foot, Southern Hills, Pinehurst, Shinnecock Hills and Pebble Beach will be added in the next 10 years. I would assume that Royal Troon, Carnoustie and Turnberry will find their way to the site as well.
Everyone calls for TPC Sawgrass but it would be a disappointment on WGT. It is a great course to play as an amateur but with it's relatively short length it would be nothing but drivers and wedges on WGT. The 17th looks tough but in reality it is a 135 yard shot to a huge green, on WGT it would be an easy birdie hole every time. Augusta National is a good course but I don't believe the membership would ever let WGT on the site to do the photos.
