It actually is coming out Monday morning, however it has been leaked from a server with incorrect folder permissions. It has been confirmed authentic and includes the sha1sum's. The updates won't be available until Monday, but the O.S. is here if you want it.
This thread splits the discussion of not yet officially up Fedora Core 5 in this thread. So I close this one. Who finds this thread can continue there.
PS. ingvildr, I move(d) your question to that the other thread.
