Looks like the AVR-X6400H (Europe only?) will process 13.2 channels.

@Todd Anderson got the scoop on upcoming D&M models?
I think some of these descriptions are misleading. the AVR-X7200WA states it does 13.2 processing with 11 amps. What this turns out to be is the secondary feeds you can send to another room. 11.2 in a main room and then two feeds to send to secondary rooms.
So once again the question is does the AVR-X6400H have 13 amps or 11 and two secondary feeds?
