Very true, K7XX was AKG's way of milking the last of the investment they put into the K7 series, casting and tooling machines etc. I am sure AKG invested much R&D cost into the K812. By looking at their sales on Massdrop and local store, not nearly as popular as HD800 (even after 6 years) for example or many of the other high fi headphones. I am sure AKG wants to atlest make back their investment, even if it slightly tarnish the K812 image.
World rewords the ones who try, thus gotta try for the K8XX.
AKG should also be easy to convince as they seen the sales of K7XX.
AKG also can lack of better word dumb down the K8XX, giving no Omega stand and overboard packaging. Save some money on the consumer end also doesn't compete with the flagship image of K812.
