I was fortunate enough to play and rate both courses this year. As a rater I try to get out and rate/see as many courses as possible in order to have as broad of a view as possible as well as continue to learn and appreciate the various styles and aspects in golf design. I was able to rate about 65 courses this year ranging from Washington, California, Nevada, Montana, Idaho, Utah, Wyoming, Colorado, and Texas. In fact, I was able to rate 5 of the top 10 courses from the best new private category (Carlton Woods, 3 Creek Ranch, Ballyneal, Tumble Creek, and Tuhaye).
I also was quite surprised to see 3 Creek out do Ballyneal and I'll admit I enjoy a lot of aspects of "new" design styles. But I felt it was pretty clear that Ballyneal was the superior course. I visited Ballyneal in mid-June (I don't think the course had been open long) and 3 Creek in mid-July. Obviously I can't speak for other panelists and everyone has their own opinion, but the only category I ranked 3 Creek higher than Ballyneal in was conditioning. I don't know if GD still throws that category out in the best new rankings, but I know they used to. The shaggy greens didn't bother me (although it did take a few holes to get used to) or anything, I just think the course hadn't had a chance to fully grow in as well whereas 3 Creek was pretty pristine by mid-summer.
As far as Tiger Woods goes, he has bought a lot on the property but I don't know if he has started building anything on it yet. In fact, he hadn't even visited the property as of mid-July according to the staff members we talked to.
Interestingly, the billionaires are pretty much kicking the millionaires out of Jackson 30 minutes west over into Victor and Driggs Idaho. That area used to be nothing much more than potato country, but it now has Headwaters (Gary Stephenson/Stephen Jones/Byron Nelson team design), a new Hale Irwin reversible routing design opening up in 2007, a Greg Norman course just was announced, and there is talk of two others. Could end up being a decent golf destination although the season is quite short.
