Slashdot linked up news of yet another potentially unexplored tomb found in the Valley of the Kings. The information came from the same survey that discovered KV63, which turned out to be a cache of burial supplies. In the article and in the comments, it's been noted that this is just a potential tomb. The place is supposed to be littered with burial shafts dug and then abandoned for reasons both obvious and obscure.

Still, should be worth a look.
