At this point, I don't trust any of their "before production" specs or marketing. The PR2 was a greatly diminished device by the time it came to market.
The 32-bit stereo issue with the PR2 was either an implementation or (more likely) a patent issue; notice how none of Zoom/Tascam/etc offer 32 bit stereo on their pocket-sized, XLR-less recorders (which, quite frankly, is where I need it). I wouldn't expect an issue on a larger recorder, again, given everyone else already does have it (though, that's not saying anything of the AES, of course).
