Impress Watch has gotten their hands on a Canon HV20 and has posted a review with lots of sample grabs and videos. I don’t really know what it says, but Engadget has a summary.
It’s interesting to learn that it supports the xvYCC color space over HDMI, which has a significantly broader spectrum of viewable colors, as compared to sRGB. There are a number of displays hitting the market now that can take advantage of the wider range of colors, so it’s nice to see devices capable of outputting it.
