He didn’t say if there was any controversial information on them? and why would he announce it before he had them?
Pinging unspun who might be able to answer your question.
IMH-but-informed-O, Ed Hale has learned that if he can do a big "Al Capone's Vault" announcement every week or so, he can gain enough attention to float along and keep stringing people along, even though people catch on to his snake oil. He is trying to gain more attention than he loses, though he has lost credibility among those who really look into the history of his shams and hoaxes.
It goes way, way back and many have been in and out his program, etc.
