Panasonic is now shipping the AV-HS300G, a DC powered HD/SD switcher. I don’t know much about this product, but I’ve very interested. It doesn’t look like it’s as all-in-one as the Anycast, but the MSRP is $7999 which puts it in a whole different price range. This could be an ideal solution for doing field shoots with the canon XL-H1. You still need a separate way to record the video,

This demands more investigation.
