For me, I find that video switching is at the heart of a pre/pro. Most TV's do not have great speakers in them and are used as monitors with the video channel being directed to the display and audio being directed to external speakers. I would find it difficult to have a SS system with 4 or more outputs going to an HDTV which may have only one or two HD inputs. You would be asking for another device to do the video switching anyway, why not have the audio and video being switched by the same device?
