What exactly do you mean?
Wikileaks got 95000 secret documents. The Pentagon knows about this, and they know exactly which documents Wikileaks got. The vast majority of the 95000 documents contained no really interesting information and was soon released. But among the remaining and yet unreleased 15000 documents there seem to be some really scandalous documents that the Pentagon are extremely scared about. The US government has never been a big fan of Wikileaks, but since they know about the 95000 documents it seems that they are trying absolutely everything to stop Wikileaks from releasing that information.
It seems like the people behind Wikileaks are starting to take this really seriously, they even seem to see the possibility of dying in staged "accident" as possible. That's why they decided to use the remaining documents as a kind of life insurance. They released the remaining 15000 documents, but they did not release the password required to decrypt the documents yet. Wikileaks is pretty much saying "If anything should happen to one of us, we just have to publish a short password and you are in serious trouble Pentagon".
From the size of the file, it seems extremely probable that it contains media. I suppose there are some really scandalous videos, maybe even worse than the Guantanamo pics.
