I wonder if HK is very very understaffed. Why would it take sooooo long to release this AVR? I am wondering how many bugs will be there from the get go though. There were several with the 745, the 247/347, and the 254/354. Also, is there a 645 equivalent coming out too. I am still happy with my 745 but eventually I might buy a new one for true 7.1. Currently, I am using the 745 only for audio and use a HDMI switcher/splitter to get 1080p24 video directly to my projector. But I am limited to 5.1 PCM since 7.1 PCM is not available on the 745.
