philspace: Muirfield would be a wonderful addition to WGT - it's a beautiful course with some of the best Par 5s around. Given WGT's long-term collaboration with USGA and R&A it remains to be seen whether they will add any full stroke play courses other than those hosting the US Open and The Open.
Wish I could say I believe in the long-term cooperation with the R&A. Last year when they did the virtual Open, the announcements did not betray anything more than that it was connected with the 150th Open. There are independent reports of filming having been done for WGT at Royal St. George's, but no hint from WGT or the R&A themselves that we might actually get that course or, later, the other ones in the Open rotation, such as Muirfield. We shall see!
