It has, and I think you can buy the professional kit for all CI models. In the far East region they offer pre-outs for the entry models such as the 2310/2311 but no CI, here in NA they offer CI even for the 231X but no preouts.
Anyway, this thing is so amazing on paper. It is also the first time Denon actually specified 4 ohm capability in their mid range MCH AVR. I really wonder how the 4312 could top the 4311 if they are to keep it at the same price point. There isn't a new feature that they can add right? So may be they can put back some nicer quality components (the look and theoretically speaking) such as better DAC in the 4312, wifi, Advanced AL processing, and good plated connectors, but then it would be in the 481X territory.
Not that it is important but what is still puzzling is whether the 4311 has the Burr Brown 1791A like its predecessors or the AK4358. At launch time Denon's website gave no information on the VP and DAC so people speculated they no longer had the ABT and Burr Brown DAC in it but now the US website (the only one) does mention the 1791A. It could just be an error though. Again, I believe a few dB difference in dynamic range and S/N in the DACs won't make any audible difference as they are not the bottle neck anyway. It is a bit like gold plated terminals/connectors, just nice to have but makes no real world difference.
