Does it actually change the response, at all, I wonder? 7.1a is known, and being independently audited anyway. (It looked pretty good back when I took a look at it, although that wasn't 7.1a and that was a more cursory look than this thorough audit process.) No duress can change the fact of what the code does (although it could change what the site serves, what the 1024-bit DSA signing key signs...). 7.2 really isn't useful for that, at all.
Be interesting to see what ultimately comes of all this mess; maybe someone will fork it from 7.1a (won't be me: build process is way too hairy and licence is troublesome even from back when it was a EFTM fork), or maybe people will move to Diskcryptor or something and improve/audit that (it _is_ under a better licence).
No matter what actually happened - or happens - it's a huge shame. TrueCrypt was practical, effective, easy-to-use, and strong when used properly (as far as I know), with some (now sadly-removed) good documentation on how to use it correctly and what it can and can't protect against well. I really hope this débâcle doesn't drive people to switch to weaker crypto.
As many have pointed out, BitLocker - even if it's faithful - isn't available on many editions of Windows, isn't cross-platform, and only really supports the equivalent of keyfiles if you're not packing a TPM. It's a poor substitute for the ways many people use TrueCrypt.
LUKS is much better, although OS support isn't anywhere near as easy-to-use, and I'd say broadly equivalent with aes-128-xts/aes-256-xts, except that LUKS has an clear-identifiable header (dm-crypt doesn't have to) and TrueCrypt (unless you have the passphrase) doesn't. (Whether that's important is doubtful: a disk full of random data looks 'probably encrypted' to anyone who'd care to look and to the guy with the 5$ wrench or jackboots, that's good enough.)
I can't comment on the Mac one, never really taken a long look.
It would also be interesting to see similarly close audits of the OS built-ins. I know I'm curious about the exact changes Windows 8 made to BitLocker, because they were fairly extensive internally. Maybe I'll take a look. Maybe you should, too.
EDIT: I also didn't realize that you had replied to my original comment, sorry about that.
