Fair request by itsthetodman et al. as members have been asking for more pins on the courses quite often. IIRC, WGT stated it was on their list of things they wanted to do this year. In fact, according to this post from a couple of years ago we should be seeing new pins on Oakmont for the VUSO this year:
WGTNiblick: Yes, you will get a new set of pins for Oakmont
for the U.S. Open in 2016. We have another set of pins that we have
not used yet.
Hopefully more as there are six WGT(not countingTruGolf) courses with only one pin placement.
ApexPC: For some of the courses WGT would have to return and make more photographs
Which ones? Totally unnecessary IMO since I believe they have already shot 3 pin locations on each course. See MisterWGT's statement on this page, 3rd post down.
MisterWGT:
We shoot multiple pin locations and
have done so for every stroke-play course.
Couple that statement with WGTNiblick's "We have another set of pins that we have
not used yet." and Oakmont already had 2 pins. Then they shot at least 3 pins on every stroke-play course as part of their process.
