Don't think anything is known yet and those that know something are probably under an NDA.
You are right of course, nobody in their right mind would take a job without knowing anything about the package, but you can still apply and if the package doesn't fit just dont pursue it further. During the Application process you will most probably given the relevant information, however i would think it will be subject to change in any case as there is at least the Lufty branch of Vereinigung Cockpit (german pilot union) involved and probably some kind of DHL thing as well.
