DVDO Edge has been around for a while, although it broke new ground in bang for buck in video upscalers. Gees, I remember the Faroudjas of yesteryear at something like $5k, but that was yesterday. Now you're seeing upscalers in recievers, but I'm not sure of their quality.
Some food for thought: Higher end non-HDMI recievers and pre/pros are selling for peanuts now. So one might couple a great sounding older unit with an Edge and have a really nice setup that will upscale all your video sources for not a lot of coin.
This thing fills a narrow but worthy notch in the AV world. I was able to stair-step upgrades, get upscaled video and video switching, two things my Theta CasaNova lacked. And even after sidelining it, I still have a good upscaler.
