I suspect that they will push up the tee box on #1, perhaps the 30+ yards suggested by Tom, which will allow for one of those massive grandstands to be built on the back half of the tee box. If I recall, in prior Opens, there were no grandstands around the first tee as at most other venues.
Pushing the tee forward will actually make the drive a bit more challenging for the long hitters, bringing the dogleg that much closer. I suspect that many will hit a 3 wood. From the front tee box and under firm conditions, the long hitters will be able to get a turbo boost kick at the beginning of the downhill portion of the fairway.
The article is incorrect, holes #1 and #17 run in the same direction, so it is difficult to assume that 17 is "into the wind" and 1 is "downwind". The green of #1 is quite exposed from winds from NNW and you typically don't feel the breeze on your approach shot.
The area right of #17 is not normal shaved, usually thick rough. The green slopes sneakily hard in the front right quadrant and if the hole is located there, and with a shaved bank, it is possible that some putts could roll off the green.
