I stumbled upon this by chance when I downloaded the 2011 AKG catalogue. Strangely enough, I saw the picture and realized it was a new model that hasn't even been announced on the AKG personal audio homepage:

Someone posted this find in Head-fi as well, but they commented saying "it's positioned above the K701". I highly doubt this means that it's the next headphone to replace the K701... heck, that's what the Q701 is for. Plus, it looks a little too laid-back in appearance for me to look like a top-of-the-line model for their Hi-Fi cans. The numbering doesn't make much sense either for it to be their best.
Chances are, they probably put it in front to bring it to our attention - and it DID work. I'm interested to know how these sound, as I'm guessing it'd be their entry-level for the hi-fi cans.
EDIT: Another shot of the specs increases my suspicions about these cans.
