This is very interesting. Have Denon finally conceded that the Mk 1 is flawed. I have still not replaced my "Mk 1" so I eagerly await this development.
It definately isn't the 3800 because it lacks the DVD audio out sockets.
The two sockets to the left of the power socket look very similar to the "room to room" sockets that appear on the back of the 3800.
