It could be but don't think it will take that long! The others have already been launched and the 280X usually is updated after the 380X. Let's see! Can't wait!
The man at my local Audio-t said don't hold your breath, and it would probably be a slightly reduced version of the 3802, maybe £150 cheaper???? If you're in the market, don't wait.
There was a link a while ago to tentative specs for the 3803 (though how reliable it is, not sure). Seemed to have new DAC´s and pretty much that was about it. Best wait until Denon release the proper specs, keep an eye on the Denon USA website. www.denon.com
