I assume that Tiger Woods via EA has an exclusive contract with Augusta National for the use of the name and the course. WGT would require pretty much unlimited access to the facility for all the photos and I can't see that happening.
I would be happy to see them bring forward some of the US and British Open courses from the past 25 years that aren't on the rotation for the next 5 years. I also don't understand the theory on the CTTH / BLITZ only courses that have been recently added, like Harbour Town. If you aren't going to make it for stroke play don't waste the time, energy and money to put it on the site at all and why did the Pebble Beach CTTH courses go away, I think we had 3 of those and the Open will be there in a few more years.
