Looks like your wait for an HDMI 1.3 receiver is still a few months away. Denon has announced its new line of A/V receivers and although they'll all have HDMI 1.3, chances are we won't see them till mid 2007. In addition to 1080p pass-through, most of the models will come with Dolby Digital Plus processing whereas some of the high-end models will include onboard Dolby True HD and DTS-HD Master Audio decoding. You already know where we stand on the HDMI 1.3 debate, but if your home theater must have the latest and greatest, you can expect to see Denon's new HDMI 1.3 receivers come June 2007.
