I believe we’ll see the so-called 1st emperor’s tomb opened within a decade at most. The Chinese are going to need a refresh to keep the tourism dollars flowing in. They have defaced the pyramid tombs in the Chinese interior, presumably a party policy thing rather than indicating their discovery of some cultural history that doesn’t fit their official narrative.
The other major undiscovered site I’d like to see found is Genghis Kahn’s tomb. The Mongols buried him and then erased all signs of it by running horses over and over the burial site to prevent its re-location.
There has been an expedition looking for its location for several seasons, but with no luck
But the technology we have today enables us to find long buried structures via satellite photos. A young female archeologist has already found hundreds of unexplored sites in Egypt including some promising unknown pyramid locations.
Well, I guess I’ll never see it. But I have seen the Terracotta Army a number of times. Once at night. Interesting.
