Oh come on this is ridiculous, either OS4 is right or its wrong??? if its right why has it not been released to current Audya owners, surely they are entitled after all this time to get it now. If its not right, then please stop playing these childish marketing games and start being honest about what and why its not here OS4, looked great sounded great, but i can't help but thinking there is more to the Ketron story thus far, its been a long time, i mean years!!
