They’d better open it soon before the moslems blow it up.
They'd be more likely to loot it -- but my quasi-educated guess is that there's going to be very little in those chambers, and definitely no Nefertiti. Naturally, I'd gladly be wrong about this. Tut died suddenly, and was not on the throne long; his burial was rushed, and there's even a peculiar scene on the wall of the tomb showing his successor, Ai, doing the burial rites. Nefertiti would not in any case have been buried in the V of the Kings.
Reeves has something of an obsession about finding Nefertiti. When he did his ground-penetrating radar survey in the KV, ten or so years ago (not long before he was suspended from being able to work in Egypt, over some bogus allegations of antiquities smuggling), and located what is now known as KV-63 (and another 'hit' dubbed KV-64), he speculated that the pit tomb could be Nefertiti's.
