Perhaps Washington National is worthy as a tournament course, but I'm skeptical. I can think of several others in the area that I would rather play, particularly considering the green fee.
As for Sundoon, I worry how the wind will affect its popularity, and therefore its viability. Wind makes for an interesting round, but I think the "average Joe" will avoid any course where the wind constantly blows hard - and I'm betting that's the kind of course they'll get.
