I can think of some reasons he would not “just release the story now”; he may have legal reasons or he wants to insure his safety thru whatever mechanisms or like Glenn Beck he is now in it just for the money, (I hope that is not the case) only he knows; we are left to speculate, it has been in the past his MO; yet he has always produced; I can only trust his reputation.
Yes, I guess its gotta be something near earth shattering to not just preannouce a story, but then to top it off with “I’m in fear for my life”. Although, not sure what they can tell us anymore that we will knock us out of our seats...
