I haven't got a clue and really want to know now. It's actually irritating me they didn't smash through right away.
I guess the best we can hope for is being a tomb completely packed to the rafters of gold an duels. Like they said tutankhamun having a silly amount of gold etc and he was a pretty insignificant pharaoh. Surprised they just don't use some mega good sonar or something to scan stuff. I mean isn't it really good these days.
