Rumour has it that the next course to be made available by WGT soon, is going to be the Pauma Valley Country Club.
It seems that they have listened to all those complains about balls lipping out and not going in.
Therefore it seems that this new course will feature 15" holes.
A video of how the greens will look like can be seen here:
