According to a German researcher, Mattias Schlenker, we are to expect that the reason for TrueCrypt's recent shutdown is not a National Security Letter, but a serious security flaw in how TC container files are created on Windows.
He expects the flaw to become public within a week.
What gives this chap some credibility is that he's one of the developers of "desinfec't", a Knoppix-based live Linux that comes with several virus scanners and is distributed by well-renowned German computer magazine c't (whose mother company/publishing house, Heise, hosts the forum where he made his announcement).

Some correction about Desinfec't: It is not based on Knoppix, but on Ubuntu. The previous, Knoppix-based tool was called Knoppicillin.
The Tao of math: The numbers you can count are not the real numbers.
