My understanding is that Steve Jobs made that up on the spot, and of course he could get away with that because he was Steve Jobs (I can't provide a citation, unfortunately--think I heard it from Gruber or the ATP guys on a podcast). Tim Cook probably wouldn't do something so impulsive based on temperament, and his direct reports would probably not risk it. So I suspect this is a considered announcement.
