It will more than likely follow the path of the elm. There will be a lot of young trees with a bleak limited future. They won't be gone, but you won't find many like the ones Rich found. Save the seeds if you find some. After the ash numbers fall off, so will the beetle's.
Best case, there will be pockets of mature trees that the beetles don't find or can't get to. There has to be some environmental variables that they can't deal with, maybe forested islands in larger lakes might get lucky. Some of their top predators are wasps and hornets, but we tend to kill those when we see them nesting in our space.
We could always crop dust the woodpeckers with bong hits and hope they get the munchies.
