The S-boxes were hardened against differential cryptanalysis long before it was publicly disclosed as a method (about a decade), largely because they got the team at IBM work on DES to keep the secret.
So it's entirely within reason to think the NSA has the potential to be a decade ahead of the public on matters of cryptography.

They eat their own dogfood, too, and move glacially slow: conservativism and military procurement, yay. (One of the Suite A's is basically LUCIFER without the training wheels, a bigger block, and more parity.) They really aren't as far ahead as you think. What they do have is an absolutely colossal budget, and that helps a lot, especially when they get to cheat, bribe, etc, and try to convince people to use crap stuff that even I could probably break, or stuff on the verge of that (like RC4).
