It is an interesting feature set, but I suspect the market for it is prohibitively small for anybody to pursue development. Once you include HD video switching, you enter the realm of home theater. Most people who have multiple HD sources and separate speakers are going to pursue at least some basic surround system, which is probably why we don't see stereo integrated amps with any sort of video switching. And once you go to multichannel, you introduce so much digital processing that we find ourselves far removed from the domain of the classic integrated amp.
