Actually I asked him this very thing. After all it's been a few years.
But he pointed out that the full force of the cryptographic community's
analysis was spread out over several candidates. Now that only one has
been selected he said NIST/NSA wanted give it 1 year of focused scrutiny
by the community just to make sure nothing popped out. However the
problem with talking with a cryptanalyst is that they always seem a bit
pessimistic about any cipher they are analyzing.
