Yes, but he's been saying that since the very first articles and interviews on Snowden. This is not new information.

Has he laid out in such stark terms, though? He has been saying the documents could cause "grievous damage" or something along those lines, but that's a far cry from "more damage to the US government in a minute alone than anyone else has ever had in the history of the United States."

Yeah he did get a bit less subtle about it in that interview. Anyone's guess as to whether that was a calculated change or just speaking off-the-cuff.

Discussing Greenwald is like playing Calvinball.

I don't know what you're talking about. Maybe it's you.
