Don't expect any improvements in the manuals. Just compare the press release with the Denon website and see the confusion already brewing. From just a cursory review, there are contradictions in the capabilities of the 4310 re (1) video processing, (2) HD Radio, and (3) Audyssey format - at a minimum. Not that anyone cares about those...right? But the pricing does confirm that that for whatever reason, the 3808 is now the 4310, etc - unless the price of the 4000 series dropped by 1/3!
