The unofficial launch schedule guesses the launch will take place sometime in October. If your info about the tracking ships sailing two weeks ago is accurate, then the launch could take place real soon. Speculation is that this one might carry some dogs to test the life support systems. Of course, there's always the possibility that humans could be on board but the Chinese seem to be using a deliberately conservative approach.
