I haven't heard any news on this in a couple of years. Hopefully all goes well, if indeed it all goes (I haven't the slightest clue what "all" means or the scope involved, fyi).
I played the course a ton early on to get one of my PE credits, and, while the more scenic of the two, I regret playing the front nine as much as I did. The back nine (which was the original nine before RTJ later added the 2nd nine that's now the front) has a lot more interesting stuff going on, especially at the greens. It'd be interesting to see it again (been forever since being on the course--maybe 2008 Senior Week?) and compare it to the rest of the evolution of RTJ's work, because that earlier nine feels closer to the Golden Age than the later one, which seems a lot more 60s era.
Certainly curious what the plans call for.
