Are you asking about dual outputs for the main zone, or a receiver with an HDMI output for zone 2? Personally, I would just enhance the listing to cover both topics, if any examples of the second configuration exist. I'm sure there will be a point where HDMI delivery to secondary zones will be expected, but it's been like pulling teeth just to get component out in zone 2.
edit - also, just because it has dual main zone outputs (if that's the what the subject is about), does that mean that both outputs can be active at the same time? One could consider that a form of "duplication", and we know how rabid the content publishers are about that bs.
