I think they're just teasing us and there's someone sat there in the offices right now laughing at all of our incorrect guesses as we over analyse everything.
That's more-accurate than a lot of the speculation one sees on here. It's not - I can assure you - a mocking laughter (no pun intended), just one that wonders where the hell certain people gets the energy to get this worked up about things to the point where they say things like: "I must get Staff Member X to answer my question or I won't know whether it's worth getting up early!"
My advice: Que sera sera.
I sometimes speak ABOUT my employer, although not FOR them.
