Well, if the next BallyNeal is already built and is Rock Creek, being private and very laid upon the land in a remote location, then we have to 'project' and speculate as to what will be also a private, and remote, and laid upon the land. Should that be limitted to US or anywhere in the world?
As to the next Bandon Dunes, I'm going with the public intention of one of the courses at Priaire Club (even though I haven't personally seen the new permutation - only Gil's routing/siting). The early possibility that even the private course will be open to properly directed public requests seems promising. So, "if" they hit a homerun, then you will get to see the next BallyNeal and Bandon all in one place.
I wouldn't discount Chambers Bay either as the next Bandon in the nature of a great public course, with a big future as it matures, and as it gains cache over time. But, that also is already a couple years old.
It would be great for golf if another very low priced, minimalist cult course like Wild Horse would be built in another part of the country, and built by one of the lesser known golf course archie/designers. It has been 10 years since the little project in Gothenburg, and it would be great for golf if a similar community project (intra state share offering or some such community funded effort) would spring forth.
As for Doak's teaser, I'm guessing it will be........on less than 300 acres, near or on water, not minimalist, yet not mega dirt mover, and somewhat sandbased but not coastal sand dunes nor links. In some ways it will be considered the by-product of a "green" sort of enterprise. It will be a hybrid!!!
