places remaining to be seen on Azeroth

After Hyjal, Gilneas and all the areas of Kalimdor and the Eastern kingdoms that used to be unreachable before the cataclysm, then all the landmasses like Northrend, Pandaria, Kul Tiras, Zandalar, the Broken Isles, Kezan and now the Dragon Isles, I'm wondering if there's still places on Azeroth we've heard about but still never saw.
