I think the NSA definitely seemed to hit a point where they calmed down. At first there was a palpable sense of "O NOE" as the NSA scrambled to discover what exactly had been stolen. And then just as suddenly, it seemed to go away. I don't think the really shocking stuff was exfil'ed by Snowden. I won't speculate what wasn't revealed, except that I think it's telling that the NSA has been asking for the ability to award high-level mathematics commendations to its workers without explaining why they deserve the award. Not much in Snowden's documents seem to fit that particular bill. The NSA isn't going to want to award the Fields Medal to someone for 0day exploits, weakening crypto infrastructure, or friggin USB hacks.
